lose three electrons
Boron looses three electrons when reacting to nonmetals like oxygen: B --> B3+ + 3e- . Another, less clear, behaviour is shown when boranes, hydrides etc. are formed.
There are many factors when it comes to Boron. If it were to form an Ion, then it would drop a total of three electrons.
boron has 2 pairs
Boron has 5 electrons per atom. Boron's electron configuration is 1s2 2s2 2p1. Thus, it has 3 electrons in its outer shell.
Krypton can gain a maximum of 2 electrons to achieve a stable octet configuration, forming the Kryptonide anion. It does not typically lose electrons.

Boron has five(5) electrons. they are arranged in two energy shells. The innermost shell ( nearest the atomic nucleus), contains two electrons , that do NOT combine with other atoms. The outermost energy shell (furthest from the atomic nucleus), contains the remaining three electrons. These three electrons are the valence electrons , and form bonds with three other atoms.
Group 2A elements typically lose 2 electrons when forming ions.
Calcium will lose 2 electrons when forming a Ca2+ ion. This is because calcium has 2 electrons in its outer shell, and it is energetically favorable for it to lose these electrons to achieve a stable octet configuration.
Boron is in group 3 and forms generally 3 covalent bonds. Because forming 3 bonds only gives boron a share of 6 electrons boron compounds are Lewis acids.

Boron has 5 electrons in total.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
It will lose 2 to form Sr2+
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'.
No atom has its electrons in its nucleus, and boron has five electrons around its nucleus.
