How many electrons would Boron with a +2 charge have?
irina [24]

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

Apply solubility rules of inorganic slats to predict the occurance of precipitation reactions?
kakasveta [241]

Explanation:

An ionic solution is when a compound's ions in an aqueous solution have dissociated. As you combine two aqueous solutions, a reaction occurs. This is when you find out whether or not a precipitate is going to form. A precipitate occurs when the ion reaction component in water is insoluble.The formation of a precipitate is an indication that a chemical change has occurred. for example if we mix clear solutions of silver nitrate and sodium chloride, sodium nitrate is formed which is a precipitate.
