-They have lower desities and melting points than alkali metals.
– They have higher ionization energies than alkali metals.
– They lose one valence electron to form ions with a 1+ charge.
– They are commonly found in nature in the lemental state.
They have higher ionisation energies than the alkali metals.
All the others are false.
the last 1 is false because i know the other 3 are so true!!!
They have higher ionization levels than alkali metals.
