Question

What name is given to those atoms which contain the same number of protons and electrons but different number of neutrons?

Answer 1

Answer:

Atoms which contain the same number of protons and electrons but different number of neutrons is called Isotopes of an element.

Answer 2

Answer is Isotope

Explanation:

• That would be an isotope. The mass number, which includes both protons and neutrons, increases but the atomic number, including just the number of protons, remains constant.
• The atomic mass is the average of all existing isotopes.
• The atomic mass of Hydrogen is 1.0079.
• This shows that the most common isotope is 1, with 1 proton and no neutrons. Deuterium and tritium are also isotopes of hydrogen with 1 and 2 neutrons respectively.
• Helium has an atomic mass of 4.003.
• This shows the most common isotope to be a mass number of 4 since the average of isotopes is so close to 4. That is two protons and two neutrons.
