The three main parts of a atom is protons,neutrons,and electrons. Protons - have a positive charge, located in the nucleus, Protons and neutrons have nearly the same mass while electrons are much less massive. Neutrons- Have a negative charge, located in the nucleus.

- electrons and protons
- protons and neutrons
- none - all are different in terms of size and mass
What are three basic parts that make up all atoms?

What are the three subunits that make up an atom?
What are the three subunits that make up an atom? Proton. What has a positive electrical charge and is found inside of the nucleus of an atom? Neuron.
Where are the 3 particles of an atom located?
There are three subatomic particles in your standard model of an atom: protons, neutrons, and electrons. Protons and neutrons reside in the nucleus. Electrons orbit the nucleus.
Where are the parts of an atom located?
We often think of atoms as tiny little spheres, but they're made of smaller parts called protons, neutrons, and electrons. The protons, and neutrons are found in the very center of the atom, which is called the nucleus. And the electrons orbit around the outside.
What are the 3 parts of an atom where are they located what are their electrical charges?
Atomic Particles Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
What are the 3 parts of atoms?
Given that these particles make up atoms, they are often referred to as subatomic particles. There are three subatomic particles: protons, neutrons and electrons.
What part of an atom is located inside the nucleus?
Protons and neutrons are found in the nucleus. They group together in the center of the atom.
Where are protons located?
the nucleusA proton one of three main particles that make up the atom. It is found in the nucleus. It has an electrical charge of one +1 and a mass of 1 atomic mass unit(amu). Atoms of any given element have a unique number of protons that is different from the numbers of protons of all other elements.
Where is the location in an atom of the lightest sub atomic particle?
Electrons – The lightest subatomic particle is the electron at 9.11×1031 kg. It is almost massless in comparison to protons and neutrons and behaves like both a wave and a particle. The electron is one of the lightest subatomic particles and one of the key components of atoms, along with neutrons and protons.
Where is most of the mass of an atom located?
The nucleusThe nucleus contains the majority of an atom's mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom's volume. The diameter of an atom is on the order of 10−10 m, whereas the diameter of the nucleus is roughly 10−15 m—about 100,000 times smaller.
Where are neutrons located?
the nucleusNeutrons and protons, commonly called nucleons, are bound together in the dense inner core of an atom, the nucleus, where they account for 99.9 percent of the atom's mass.
What are neutrons and where are they located?
Neutrons are a type of subatomic particle with no charge (they are neutral). Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force.
How are the parts of the atom arranged?
Nucleus and Electron Shell The parts of each atom are arranged to form a central core or atomic nucleus and an outer set of electron shells. Atomic Nucleus – Protons and neutrons collectively are termed nucleons because they bind together to form the nucleus of each atom.
What are the three parts of DNA?
Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: 1 Nitrogenous Base#N#Purines and pyrimidines are the two categories of nitrogenous bases. Adenine and guanine are purines. Cytosine, thymine, and uracil are pyrimidines. In DNA, the bases are adenine (A), thymine (T), guanine (G), and cytosine (C). In RNA, the bases are adenine, guanine, uracil, and cytosine. 2 Pentose Sugar#N#In DNA, the sugar is 2'-deoxyribose. In RNA, the sugar is ribose. Both ribose and deoxyribose are 5-carbon sugars. The carbons are numbered sequentially, to help keep track of where groups are attached. The only difference between them is that 2'-deoxyribose has one less oxygen atom attached to the second carbon. 3 Phosphate Group#N#A single phosphate group is PO 43-. The phosphorus atom is the central atom. One atom of oxygen is connected to the 5-carbon in the sugar and to the phosphorus atom. When phosphate groups link together to form chains, as in ATP (adenosine triphosphate), the link looks like O-P-O-P-O-P-O, with two additional oxygen atoms attached to each phosphorus, one on either side of the atom.
What are the building blocks of DNA and RNA?
Nucleotides are the building blocks of the DNA and RNA used as genetic material. Nucleotides also are used for cell signaling and to transport energy throughout cells. You may be asked to name the three parts of a nucleotide and explain how they are connected or bonded to each other. Here's the answer for both DNA and RNA .
What are the two categories of nitrogenous bases?
Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: Purines and pyrimidines are the two categories of nitrogenous bases. Adenine and guanine are purines. Cytosine, thymine, and uracil are pyrimidines.
How many phosphate groups are in a free nucleotide?
The number 5 carbon of the sugar is bonded to the phosphate group. A free nucleotide may have one, two, or three phosphate groups attached as a chain to the 5-carbon of the sugar. When nucleotides connect to form DNA or RNA, the phosphate of one nucleotide attaches via a phosphodiester bond ...
