how many valence electrons does family 1 have
Boron is located in group 3A. It is group 13 in modern notation. This set of elements have three valence electrons.Boron is in the 13th group in the periodic table. Elements in this group has 3 electrons in the outermost energy level. That means they have 3 valence electrons.
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.

Boron has 3 valence electrons.
Boron's atomic number is 5. Thus, its electron configuration is 1s2 2s2 2p1. If you add up the number of electrons in the "2" shell, which is boron's valence shell, you get 2 + 1 = 3 valence electrons.

Boron has three valence electrons.
There are two non-valence electrons in a neturol boron atom. The electronic configuration of neutral boron is 1s2, 2s2 2p1. The three electrons in the 2d shell are the valence electrons; the non--valence electrons are in the 1s orbital.
