These elements belong to different Physical and chemical properties , which means they have different and different . Sodium is an metal while neon is a gas.

Check explanation section.

Explanation:

Yes, that is true. Sodium with chemical symbol Na belongs to the group 1 on the periodic table. Group 1 elements are known as Alkali metals. Other elements in the group are Caesium, lithium, Rubidium, francium and potassium.

Neon belongs to the noble gas of group 8/0.

Sodium is very reactive and and good conductor of electricity. Sodium reacts with water for the production of hydrogen (NB: this reaction is vigorous).

2Na(s) + 2H2O > 2NaOH + H2(g).

They can react with nonmetals such as the halogens. For instance;

Na + Cl2 > 2NaCl.

Sodium is ductile and have low melting point( but high compared to neon).

Neon is not active chemically and it has no odour and no color

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
