What are Similarities and differences between alkali metals?

Answer 1

Alkali metals are group 1 elements with one valence electrons. They tend to lose 1 electron and attain stability by forming cations. They are hence chemically reactive.

Noble gases are group 18 elements. They have completely filled orbitals and hence are chemically inert.

Answer 2

The alkali metals are a common family of elements found in group 1 of the Periodic Table. This group consists of the metals, Lithium(Li), Sodium(Na), Potassium(K), Rubidium(Rb), Caesium(Cs), Francium(Fr).

Alkali metals react violently with water and give off flammable hydrogen. Their reactivity increases as you go down the group Francium being the most reactive. Also thier melting point decreases as you move down the group. The alkali metals have closer similarities between the elements than in any other group of the periodic table. For example they are all soft and silvery in colour.

Answer 3

There are no similarities. Noble gases have completely filled valence orbitals are are stable. Alkali metals have one valence electron and are reactive.

The only thing to to be noted is that, alkali metals normally lose one electron to form cations and attain the configuration of noble gas.

Answer 4

one group is a metal while the other isn't

Answer 5

Similarithjaes:

They like long walks on the beach

They have orange hair

Differneces:

Alkali metals cut themselves

Noble gases are noble to eachother

Answer 6

there are no similarities, except for the fact that alkali metals lose one electron to form cations which have the same electronic configuration as that of the noble gases.
