Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The atomic number of an elements is the total number of which particles in the nucleus?
A
neutrons
B
protons
C
electrons
D
protons and electrons
Explanation: 

Detailed explanation-1: -The number of protons in the nucleus of the atom is equal to the atomic number (Z).

Detailed explanation-2: -The atomic number (represented by the letter Z) of an element is the number of protons in the nucleus of each atom of that element.

Detailed explanation-3: -The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

Detailed explanation-4: -The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons–the atomic number–are atoms of the same element.

Detailed explanation-5: -A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below).
