What is the difference between sodium atom and sodium ion?
Sodium atom is neutral whereas sodium ion is a charged specie with a charge of +1. The number of protons and electrons in sodium atom is same i.e 11 whereas the number of protons in sodium ion (11) is more than number of electrons (10). The size of sodium ion is smaller than sodium atom. Click to see full answer.
What is the difference between Na and Na+?
Na contains 11 electrons while Na+ contains 10 electrons. Na is symbol of normal sodium atom which have 11 protons in nucleus , with electronic configuration (2,8,1) having total 11 electrons in its all 3 shells. that's why normal sodium atom (Na) is electrically neutral. But Na+ is positive ion of sodium.
What is the difference between an atom and an ion?
An atom has an equal number of neutrons as protons but at least 1 neutron (hydrogen-1). Whereas ions can vary in their numbers of neutrons since they may gain or lose one or more to become either cations or anions. 9.
What is an ion with more electrons than protons called?
An ion with more electrons than protons carries a net negative charge and is called an anion. The number of neutrons doesn't come into play since they are electrically neutral. Changing the number of neutrons determines the isotope. Ions are often formed in nature when static electricity draws electrons away from atoms.
Is Na+ an atom or ion?
Neutral sodium atom (Na) becomes sodium cation (Na+) by releasing an electron. chlorine atom (Cl) in the chlorine molecule (Cl2) becomes chloride (Cl-) by accepting an electron. positive charge on the sodium cation is balanced by the negative charge on the chloride, so the ionic compound is neutral.
What is the difference between Na atom and Na ion in terms of number electrons?
The sodium atom has 11 electrons. Sodium-ion has 10 electrons as sodium atom loses one electron to form sodium ion.
What is the main difference between an atom and an ion?
Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
What is Na as an ion?
Sodium ion (Na+) is the principal extracellular cation and solute and is essential for generation of action potentials in nervous and cardiac tissue. Pathologic increases or decreases in total body Na+ are associated with corresponding increases or decreases in extracellular volume (ECV) and plasma volume (PV).
What is the difference between sodium element and sodium ion?
Sodium atom is neutral whereas sodium ion is a charged specie with a charge of +1. The number of protons and electrons in sodium atom is same i.e 11 whereas the number of protons in sodium ion (11) is more than number of electrons (10).
Which is greater Na or Na+?
The Na+ ion and Na atom have same nuclear charge however Na+ has more 'effective' nuclear charge hence Na+ is smaller than Na. Na+ has more effective nuclear charge as it has 1 electron less than Na.
What is the difference between an atom and an ion quizlet?
What is the difference between an atom and an ion? An atom has no electrical charge. Ions have an electrical charge because they have an imbalance of protons and electrons.
What is difference between electron and ion?
Electron is a negatively charged atomic particle which is inside an atom. Ion is an atom or molecule with a net electric charge (which may be positive or negative) due to the loss or gain of one or more electrons.
How do you know if it is an atom or ion?
An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION.
Are all atoms ions?
Ions are atoms or molecules that have gained or lost one or more of their valence electrons and therefore have a net positive or negative charge. An atom can be an ion, but not all ions are atoms.

How many protons does sodium have?
Positive ions or cations are formed when an atom loses an electron. This concept can be cleared with the help of an example. A sodium atom consists of 11 protons and 11 electrons. It is electrically neutral when it loses an electron it becomes Na⁺ ion. The charge of this ion is +1
What is the central part of an atom?
Rutherford atomic model states that an atom has a central part known as nucleus and electrons are revolving around it. The positive charge of the nucleus is neutralised by the negative charge of the electrons. But his theories couldn’t give the details regarding the stability of an atom.
How many electrons does a chlorine atom have?
Negative ions or anions are formed when an atom gains an electron. For example, a chlorine atom consists of 17 electrons and 17 protons. When it gains an electron, it becomes Cl⁻ ion. The charge of this ion is −1.
What happens when an atom loses an electron?
Unlike atoms, ions are charged particle. But they also consist of electrons, protons and neutrons. When an atom loses or gains an electron, it becomes an ion. Depending upon the gain or lose, atoms can be classified as positive ions or cations and negative ions or anions
How many neutrons are in oxygen?
Number of neutrons in oxygen is 16–8 = 8. v. The arrangement of the atoms in the periodic table is in such a way that down the group, the radius of the atom increases and across the period radius of the atom decreases.
Which model did not explain the fine structure of spectral lines of hydrogen?
Bohr atom model could not explain some concepts like the fine structure of spectral lines of hydrogen, distribution of electrons etc. Somerfield modified Bohr atom model and he explained the path of the electron and gave more explanations regarding the structure of spectral lines of hydrogen.
How are molecules formed?
Molecules are formed by the combination of atoms. iv. On the basis of nuclei, atoms can be classified as isotopes, isobars and isotones. a. Isotopes. If the atoms of the same element have the same atomic number, (represented as ‘Z’) and different mass number (represented as A). They are known as isotopes.
Introduction to Atoms
- The word ‘atom’ was coined from the Greek word ‘atomos’; the meaning of ‘a’ in the word is ‘not’ and ‘tomos’ means ‘cut’. Together it became impossible to cut. Investigations on atoms have been started over a long period of time and still, it is continuing. The basic definition of atoms is “Atoms are small indivisible particles and every matter that we see are made up of atoms” The first expl…
Features of Atom on The Basis of Modern Atomic Theory
- The Modern atomic theory states that though atoms are small, they are divisible.
- Nucleus of an atom consists of subatomic particles, protons and neutrons which are collectively known as nucleons. Electrons are revolving around the nucleus in specific orbits. Since the number of...

Ions
- Unlike atoms, ions are charged particles. But they also consist of electrons, protons and neutrons. When an atom loses or gains an electron, it becomes an ion. Depending upon the gain or loss, atoms can be classified as positive ions or cations and negative ions or anions. 1. Positive Ions (Cations) Positive ions or cations are formed when an atom ...
Difference Between Atoms and Ions
- Atoms are electrically neutral, which means the number of protons and electrons will be the same. While ions are charged particles, positive ions (cations) or negative ions (anions).
- Combination of atoms results in the formation of molecules and the combination of ions results in the formation of compounds.
- Independent existence of atoms is not possible. But, ions can exist independently.
