Question

please answer its important and i need your help
These are about periodic table​

Answer 1

Answer:

1. Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

2. Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.

These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

hope this helps :)
