Question

Can someone explain the alkali metals unit to me please? I am so confused and I have a test about this stuff. Not not only alkali metals but the other metals and non metals as well. Please help me

Answer 1

Alkali metals are the first column in the periodic table, alkaline earth metals are the second column. The following columns are transition metals up to the column with aluminum. These are non-metals, the second last column is halogens and the last is noble gases
