Answer 41

They are never found as free elements in nature.

Question 42

Alkali metals are always what with other elements

Answer 42

Bonded with other elements

Question 43

What does it mean to be reactive

Answer 43

Reactivity is the the ability of a substance to interact chemically with a second substance.

Question 44

What makes an element reactive

Answer 44

An incomplete valence shell, doesn't have 8 electrons in the very outermost energy level. (Which is called the rule of octet) Atoms bond until this level is complete, atoms with few valence electron lose them during bonding, and atoms with 6, 7, or 8 valence electrons gain more electron during bonding
