yes
No. helium is chemically inert and does not combine with other elements.
Neon has completely filled orbitals. It is chemically inert and does not combine with other elements.

Metals are particularly likely to combine chemically with the halogens you listed, but I will add that almost every element on the periodic table (with the exception of the noble gases) will combine with at least some of the halogens.
Neon is chemically inert and does not combine with other elements (including itself). It exists as a mono atomic gas.
The ionic compound that forms when sodium and iodine combine chemically is sodium iodide (NaI). Sodium gives up an electron to iodine, forming a positively charged sodium ion and a negatively charged iodide ion, which then attract each other to form the compound.
Yes, elements with a full outermost energy level, such as the noble gases, are generally unlikely to combine chemically with other elements. This is because they possess a stable electron configuration, which makes them less reactive. As a result, they have little tendency to gain, lose, or share electrons, minimizing their interactions with other elements.
Helium has completely filled valence orbitals, is stable and chemically inert.
When atoms of two different elements chemically combine, they produce a compound. Such compounds include sodium chlorine, hydrogen fluorine, and barium sulfide. Note that if the elements are same, the result is a polyatomic element, not a compound.
No. Xenon is chemically inert. Hence it does not combine with other elements and is not found in food materials.
Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.
No, iodine is not a noble gas. Iodine belongs to the halogen group in the periodic table, which contains elements that are highly reactive. Noble gases are a separate group of elements that are inert and do not readily combine with other elements.
