What property describes the elements in group 1?

Answer 1

The most common property between all group 1 elements is the formation of +1 charge when participating in a chemical bond. Other properties include excellent thermal conductivity, extremely soft (maybe even liquid), luster, and relatively low melting points for a metal

Answer 2

appearance

Lithium, sodium and potassium are all soft metals that are easily cut with a scalpel or knife. The freshly cut surface is a shiny, silver colour, but this tarnishes quickly to a dull grey as the metal reacts with oxygen and water in the air. Pieces of such metals are stored in oil to prevent these reactions.

The shiny surface of sodium tarnishes more quickly than that of lithium. And potassium tarnishes more quickly than sodium. This shows the increasing reactivity of the metals as we go down the group.

density

The alkali metals have low densities compared to most other metals.

melting/boiling point

The alkali metals have low melting and boiling pointscompared to most other metals. Apart from the other alkali metals, only three metals (indium, gallium and Mercury) have lower melting points than lithium.

they react with water and chlorine with increasing

ferocity as you go down the table.

hope this helps

Answer 3

The elements in group 1 of the Periodic Table are known as alkali metals. They are highly reactive metals that readily lose their outermost electron to form a 1+ cation. They are soft, shiny, and have low melting points.

Answer 4

reactive,

bears one valence electron

shiny

electrically conductive
