In the nucleus of any atom, only neutrons and protons are present Hence the Number of Electrons in the nucleus is zero.
CONCEPT:
- Composition of an atom:
- An atom consists of protons (positively charged particles) and neutrons in its nucleus.
- The total number of protons in a nucleus is equal to the number of electrons (negatively charged particles) orbiting the nucleus. Therefore, an atom is electrically neutral.
- A chemical element is always represented using its symbol as follows: Z X A
Where x is the symbol for the element, A is its mass number and Z is the atomic number.
- The mass number A is the sum of the number of neutrons and protons present in the nucleus of the atom.
- The atomic number Z is the number of protons present in the nucleus of the atom.
