silicon prefers to share electrons forming covalent bonds
It gains
it has gain 4 electrons
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
It loses electrons.
it gains electrons.
Silicon gains 4 electrons.
It gains
No. Atoms can gain and lose electrons but seldom gain or lose protons.
it has gain 4 electrons
Covalent bonds do not gain or lose electrons, but rather share electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
Lose
When atoms lose or gain electrons, they form ions. These are charged particles.
A Covalent bond, because it takes too much energy to gain/lose more than two electrons, thus leaving the option of sharing electrons forming a covalent bond.
Se will gain electrons
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
Lose electrons is oxidation. To gain electrons is reduction.
