Since hydrogen only has an atomic number of one, there is one proton in the nucleus, therefore the nucleus has a +1 charge, for the overall charge to be -3, there must be four electrons: +1 + (4 x (-1)) = -3.
Aluminum has 3 valence electrons.
The element lithium has 3 protons and 3 electrons.
3 valence electrons
Lithium-7 has 3 electrons.
3
Hydrogen's atomic number is 1. Thus it has one proton per atom. To balance it out electrically then, hydrogen must also have one electron per atom.
Each H atom has one proton in its nucleus.
no
Indium has 3 valence electrons.
2 electrons
There are 3 electrons.
Aluminum has 3 valence electrons.
phosphorus will accept 3 electrons or share 3 electrons
Lithium is element #3, and it has 3 electrons.
yes
There are 3 valence electrons in an atom of aluminium.
There are 3 electrons in the outermost level of aluminum. Aluminum is in Group 13 and has 3 valence electrons.
