Both helium and beryllium
WebDec 16, 2024 · Chemical element helium has the atomic number 2 and the symbol He. It is the first member of the noble gas group in the periodic table and is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas. Neutrons have no charge, protons have a positive charge, and electrons have a negative charge. WebHelium, He, and beryllium, Be are both the second elements in their respective rows on the periodic table. they are not placed directly above and below each other in the periodic table because they: do not have similar chemical properties.
