number of protons

Relation Between Atomic Number and Atomic Mass - While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high a..

Atomic number = number of protons = 11Mass number = number of protons + number of neutrons= 11 + 12 = ..

Atomic number = 12Number of protons = number of electrons = atomic number = ..

The atoms of different elements, which have the same mass number but different atomic numbers are called isobars. These have different number of protons but equal sum of number of protons and neutron..

Since the positive protons in the nucleus repel each other, neutrons are required to bind the nucleus together. For lighter elements, the number of protons and neutrons are approximately equal. As the number of protons increases the force required ..

Question: Define the following terms: a) Nucleons b) Atomic number c) Mass number d) Nucleus Answer: a) Nucleons: The particles found inside the nucleus i.e., protons and neutrons are called nucleons. b) Atomic number: The number of ..

Atomic Number, Mass Number or Nucleon Number - The nuclei of atoms are made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral,..

These are the elements having same atomic number but different mass number. They have the same atomic number because the number of protons inside their nuclei remains the same. The difference in their mass number is due to the differ..

Atomic Structure and Charges - The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons..

A nuclide is any species of atom of which each atom has an identical proton number and also an identical nucleon number. Different nuclides, which have the same proton number (but different nucleon numbers) are called isotopes (isoto..
