which determines the reactivity of an alkali metal?\n○ its boiling and melting points\n○ the shininess of its surface\n○ the number of protons it has\n○ its ability to lose electrons

Answer

Brief Explanations:

Alkali metals are in Group 1 of the periodic table and have 1 valence - electron. Their reactivity is determined by how easily they can lose this outer - shell electron to achieve a stable electron configuration. Boiling and melting points, shininess, and number of protons are not directly related to their chemical reactivity in terms of losing electrons for chemical reactions.

Answer:

its ability to lose electrons
