1.	what properties pairs the elements argon,calcium,potassium,magnesium,nitrogen,neon and phosphorus in groups
Answer» Alkali Metals (Here-Potassium) LESS dense than other metals one LOOSELY bound valence electron highly reactive, with reactivity increasing moving down the group largest atomic radius of elements in their period low ionization energy low electronegativity Alkaline Earth Metals(Calcium/magnesium) TWO ELECTRONS in the valence shell readily form divalent cations low electron affinity low electronegativity The halogens and noble GASES are nonmetals, although they have their own groups, too. high ionization energy high electronegativity poor electrical and thermal conductors form brittle solids little if any metallic luster readily gain electrons Mark me as brainliest

what properties pairs the elements argon,calcium,potassium,magnesium,nitrogen,neon and phosphorus in groups

Answer»

Alkali Metals (Here-Potassium)

LESS dense than other metals

one LOOSELY bound valence electron

highly reactive, with reactivity increasing moving down the group

largest atomic radius of elements in their period

low ionization energy

low electronegativity

Alkaline Earth Metals(Calcium/magnesium)

TWO ELECTRONS in the valence shell

readily form divalent cations

low electron affinity

low electronegativity

The halogens and noble GASES are nonmetals, although they have their own groups, too.

high ionization energy

high electronegativity

poor electrical and thermal conductors

form brittle solids

little if any metallic luster

readily gain electrons
