Alkali - correct answer ✔✔Group 1; most reactive metals; found in compounds (bonded to others); soft,

metalloids - Sn Pb - metals; 4 valence electrons; Carbon is essential, living thing have this
Nitrogen Fam - correct answer ✔✔Group 15; 5 valence electrons; mixed grou (nm, m, met); Nitrogen gas
80% of atmosphere and is not reactive; 2 atoms of N bonded together; building blocks of protein; need it
in food; phosphorus is highly chemically reactive and is used in matches and flares
