Naming Review

What is the name of Li⁺

• lithium ion

• lithium

• lithide

• lithium (I) ion

Answer explanation

For cations/metals (which are paw-sitive), name the metal then add the word ion.

If the metal is a transition metal, you must use roman numerals to identify it's charge.

For anions/non-metals (anions looks like onions, which make you cry, which is negative), change the ending to -ide.

What is the formula for beryllium ion

• Be⁺²

• Be

Answer explanation

To find the formula when given the name, find the symbol for the element, then find the row at the top of your periodic table called oxidation number (this should have a + or - number). Combine the two items together, with the charge as a superscript (Superman flies up in the air, so the superscript is upper right).
