Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
45
It will lose 2 electrons.
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
Ga3+ has 31 - 3 = 28 electrons
Se will gain electrons
It has 31 electrons. The easiest way to find an electron is that the atomic number tells you how many protons and electrons on the periodic table. It will change if the element is an ion which will gain or lose an electron.
Gallium is a non metal element. There are 31 electrons in a single atom.
