Forms of the same atom that differ only in their number of neutrons are called isotopes. Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons.

How do you find the mass number of copper?
-So, the atomic mass of copper is 63.5 and atomic number is 29. -Atomic number is always equal to the numbers of electrons or protons present in the neutral element. Hence, the number of neutrons in the copper atom is 34. Copper has mainly two isotopes in nature which are denoted as 6329Cu and 6529Cu.

Which element has mass number of 65 and 36 neutrons and charge of 1?
65-36= 29 protons. Since we got 29 protons, go to the periodic table of elements and find number 29 and you will get your element symbol. The symbol will be Cu, or Copper.
How to determine the stability of an isotope?
To determine the stability of an isotope you can use the ratio neutron/proton (N/Z). Also to help understand this concept there is a chart of the nuclides, known as a Segre chart. This chart shows a plot of the known nuclides as a function of their atomic and neutron numbers. It can be observed from the chart that there are more neutrons than protons in nuclides with Z greater than about 20 (Calcium). These extra neutrons are necessary for stability of the heavier nuclei. The excess neutrons act somewhat like nuclear glue. Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3.
How are atomic nuclei determined?
Properties of atomic nuclei (atomic mass, nuclear cross-sections) are determined by the number of protons and number of neutrons (neutron number). It must be noted, especially nuclear cross-sections may vary by many orders from nuclide with the neutron number N to nuclide with the neutron number N+1. For example, actinides with odd neutron number are usually fissile (fissionable with slow neutrons) while actinides with even neutron number are usually not fissile (but are fissionable with fast neutrons). Heavy nuclei with an even number of protons and an even number of neutrons are (due to Pauli exclusion principle) very stable thanks to the occurrence of ‘paired spin’. On the other hand, nuclei with an odd number of protons and neutrons are mostly unstable.
How many protons does copper have?
Copper is a chemical element with atomic number 29 which means there are 29 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
How many electrons are in a copper atom?
Therefore, the number of electrons in neutral atom of Copper is 29. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
Why do neutrons stabilize the nucleus?
Neutrons stabilize the nucleus, because they attract each other and protons , which helps offset the electrical repulsion between protons. As a result, as the number of protons increases, an increasing ratio of neutrons to protons is needed to form a stable nucleus.
What happens when there are too many neutrons in a nucleus?
If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoes radioactive decay . Unstable isotopes decay through various radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture.
What is the difference between neutrons and atomic numbers?
The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z. For stable elements, there is usually a variety of stable isotopes. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons.
What is the total electrical charge of the nucleus?
The total electrical charge of the nucleus is therefore +Ze , where e (elementary charge) equals to 1,602 x 10-19 coulombs. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.
What are the oxidation states of copper?
Possible oxidation states are +1,2. Copper forms a rich variety of compounds, usually with oxidation states +1 and +2, which are often called cuprous and cupric, respectively. Copper compounds, whether organic complexes or organometallics, promote or catalyse numerous chemical and biological processes.

What is the atomic mass of copper?
The atoms of natural copper are about 70% and 30% . Thus, the relative atomic mass of natural copper (63.5) lies between 63 and 65, but closer to 63 because that is the relative atomic mass of the more abundant isotope.
How many protons does copper have?
All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons (Figure 4).
How are the two isotopes written?
The two isotopes are written, and where the mass number and atomic number precede the chemical symbol as a superscript and subscript, respective ly ( Figure 5. 66. ). The mass number of any isotope is equal to the relative atomic mass of its atom, rounded to the nearest whole number. The atoms of natural copper are about 70% and 30% .
What are the two types of atoms called?
The two different kinds of atom are called isotopes of copper. The neutron has a mass very similar to that of the proton, so the two isotopes differ in mass. The sum of the numbers of neutrons and protons for a particular isotope is called the mass number.
