Answer:

1.To illustrate chemical reactions and the elements and compounds involved in them, chemists use symbols and formulas. A chemical symbol is a one- or two-letter designation of an element. Some examples of chemical symbols are O for oxygen, Zn for zinc, and Fe for iron. The first letter of a symbol is always capitalized.

2.An element's location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block.

3.Alkali metals and alkaline earth metals both have intense chemical reactivity to air and water. ... Alkali metals are very reactive because they contain a single valence electron.
