Boron is an elemet in group 13, hence it has three valence electrons.

There are three valance electrons. These are the electrons in the outer shell if it is not full.

The as yet undiscovered and fictional element hugeonium will have many electrons, possibly in excess of 125.

there are 5 electrons in boron atoms.

The # of Valance electrons in the oxygen famly is 6

By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons

On the periodic table there are groups, 1A-8A. The nuber tells you how many valance electrons the elements have. Carbon is in group 4A, so it has 4 valance electrons.

No atom has its electrons in its nucleus, and boron has five electrons around its nucleus.

Oxygen has 6 valance electrons. You can figure out the number of valance electrons for any main group element (Group IA-IIA and IIIA-VIIIA) using the periodic table. Group IA- all elements have 1 valance electron Group IIA- all elements have 2 valance electrons Group IIIA- all elements have 3 valance electrons ... Group VIA - 6 valance electrons ... Group VIIIA- 8 valance electrons The number of valance electrons is equal to the group number (which is shown in roman numerals)

Boron is in group 3, so it has 3 valency electrons.

There are 3 valence electrons in Boron..Remember valence electrons are in the outer shell
