How many valance electrons does an atomof boron have?
Boron has three valance electrons. Boron also has three electtrons in outermost energy shell. The 'Valance' number of electrons tells you how many bonds will form between boron and other atoms. Compare with oxygen . Oxygen has two valance electrons . However, oxygen has 6 electrons in its outermost energy shell. This means that oxygen will form two bonds between other atoms. Thus leaving four electrons uncombined; they are known as 'lone pairs'.
How many electrons are in the valence shell of He?
There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.

How many protons can fit in the third shell of a regular atom?
Protons won't be found in an electron shell. They are concentrated in the nucleus.
How many protons does atoms have?
There are 9 protons in the element fluorine.
Why do you think non metals tend to be good at sharing electrons?
All atoms are more stable when their outer most electron shell (valance shell also refered to as a valance orbital but it is slightly different) is full of electrons. Non metals generally have almost full valance shells and it takes less energy to gain a few electrons to reach the stable full outer shell than to lose many electrons to form a stable full outer shell. Take F as an example - it has 7 electrosn in its outermost shell and this shell can fit 8. It will accept 1 electron more easily than losing 7.
How many shells are in hydrogen?
Hydrogen has one shell with only 1 electron on the valance shell.
