How many protons and electrons are in Si4+?

Silicon (Si) has an atomic number of 14, which means it has 14 protons in its nucleus. In a neutral atom of silicon, the number of electrons is also 14, balancing the positive charge of the protons.

When silicon forms a Si⁴⁺ ion, it loses four electrons. Therefore, to calculate the number of electrons in Si⁴⁺, we subtract the four electrons that have been lost from the original 14 electrons:

Electrons in Si⁴⁺ = 14 – 4 = 10.

So, the Si⁴⁺ ion has 14 protons and 10 electrons.
