What is the chemical similarities of group 1 of the periodic table?

Answer 1

These are highly reactive metals with a strong tendency to participate in ionic bonding by forming cations with a charge of +1.

Answer 2

they are very reactive. Their reactivity increases down the group.

They tarnishes in air quickly to form R(OH), alkaline solution, where R is grp 1 element and their salts are soluble in water.

Answer 3

i. They are good conductors of electricity and heat ii. They are soft metals (lithium is hardest, potassium is softest) iii. They have a low density (compared to other metals) iv. They have low melting points (compared to other metals) v. They burn in oxygen or air with characteristic flames to form white solid oxides vi. They react vigorously with water to give a metal hydroxide as well as hydrogen gas. Potassium is most reactive with water vii. They react vigorously with halogens viii. Reactivity increases as you go down the group Source --> self notes for my examination

Answer 4

These are highly reactive metals with a strong tendency to participate in ionic bonding by forming cations with a charge of +1.

Answer 5

The elements of group-18 have fully filled valence shell. They are stable in nature.

Answer 6

They all have one valence electron
