Arsenic is not highly reactive, because it is unaffected by air, water, and most acids and alkalis.
A substance that has high reactivity displaces dissolved oxygen.
Phosphorus. Due to its high reactivity, this element can't be found in its free state.
no
Arsenic does melt, but has a very high melting point of 1503°F.
potassium sodium
A substance that has high reactivity displaces dissolved oxygen.
The reactivity of iron is quite high, as it reacts by coming into contact with moisture in the air.
Phosphorus. Due to its high reactivity, this element can't be found in its free state.

No, arsenic is a metalloid, which means it has characteristics of both metals and non-metals.
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
yes
potassium sodium
Forms easily with other substances.
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
Some characteristics that indicate high chemical reactivity for one or more reagents include a high tendency to undergo chemical reactions, instability, high electronegativity, and high reactivity in the presence of other substances or conditions such as heat, light, or catalysts. Additionally, a high reactivity may be indicated by the presence of reactive functional groups such as alkyl halides, carbonyl compounds, or highly polarizable atoms.
