How many electrons would Boron with a +2 charge have?

Chemistry
1 answer:
irina [24]3 years ago
4 0

5 electrons

Boron atomic number 5 has five electrons in its ground state.

Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.

Explanation:

The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom.

Boron number 5 has five protons and therefore as a neutral atom also has five electrons.

Boron has an electron configuration of

1s22s22p1

The most stable electron configuration for Boron is

1s2

+ 3 charges. By losing three electrons Boron can achieve the stable electron structure of Helium

How does a scientist form a hypothesis?
MrMuchimi

Explanation: <em>The hypothesis is a prediction, but it involves more than a guess. Most of the time, the hypothesis begins with a question which is then explored through background research. It is only at this point that researchers begin to develop a testable hypothesis.</em>

(Unless you are creating an exploratory study, your hypothesis should always explain what you expect to happen)
