What are the ionic charges?
An ionic charge is the positive or negative charge associated with an atom. The charge is dependent upon the electron configuration (number of electrons) of an atom. In general, positive ionic charges (cations) are found on the left of the periodic table and negative charges (anions) are found on the right side.
Which ion has a charge of 2 -?
Metals form positive ions (cations). A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+.
What is the ionic charge of boron?
+3
Boron would have a +3 charge.
What are helium ions?
Ionised helium (He+), also known as He II, is a very high energy material able to extract an electron from any other atom. He+ has an electron configuration like hydrogen, so as well as being ionic it can form covalent bonds.
How do I know what charge an element has?
For a single atom, the charge is the number of protons minus the number of electrons.
What is the charge of an ion with 16 protons and 18 electrons?
The element with 16 protons is sulfur, with the symbol S. An ion of sulfur with 18 electrons gives sulfur a charge of 2−. The sulfide ion is S2−.
What has 82 protons and electrons?
The atomic number of lead is 82, which means this ion contains 82 protons. Since it has a charge of +2 , this ion must contain 80 electrons.

What does Roman numeral notation indicates charge of ion?
Roman numeral notation indicates charge of ion when element commonly forms more than one ion. For example, iron(II) has a 2+ charge; iron(III) a 3+ charge.
