The mass number of an atom : 26
<h3>Further explanation</h3>
Given
12 protons, 14 neutrons, and 12 electrons
Required
The mass number
Solution
Inside the atom there are 3 sub-particles, namely protons, neutrons and electrons. Protons and electrons are present in the atomic nucleus while electrons move around the atomic nucleus through energy levels in the atomic shell
Atomic number = number of protons = number of electrons
Mass number = number of protons + number of neutrons
Input the value :
Mass number = 12 + 14
Mass number = 26
Hen two electrons occupy the same orbital, they always have opposite spin. No other knowledge about electron spin is needed for A-level.) Only when the 2s is filled, can the 2p sub-level fill. With the next six elements (boron, carbon, nitrogen, oxygen, fluorine and neon) the three 2p orbitals are filled.
