Same group element have same Valence electron and behave similarly in Chemistry.

Explanation:

For example. First group elements Alkali metals:- H, Li, K, Rb, Cs, Fr

Valance electron will take part in forming a bond with other elements and compound will form. All the above-given elements (H-Fr) have valence electron 1 in outer most 'S' shell. All have electronic configuration S1

Behavior: Since valence electrons are the same so the behavior of all the elements in this group is the same. All are metal (from Li-Fr, except Hydrogen), all are very reactive, does not found in native state in the environment, and all react with water.

What is the correct term for a shorthand notation that places chemical formulas and other symbols in a specific format in order

balandron [24]

Answer: Chemical equation

Explanation: In writing a chemical equation, the correct formula and symbols of the reactants are written on the left hand side of the equation while those of the products are written on the right hand side. A horizontal arrow is drawn between the two sides to indicate the direction of the reaction.

Example: Na + Cl -> NaCl

How do you know whether to use a lone pair or a double bond when drawing a Lewis dot structure?

Charra [1.4K]

Well that depends on the central atom. Remember each bond indicates another electron that is being shared with the central atom.
So CO4, carbon would be your central atom, with the 4 oxygen around it. There would be no double bonds because carbon only requires the 4 electrons provided by the oxygens, because of its location on the periodic table.
Nitrogen on the other hand is different. It's found in group 5 (5V) and has 5 valence electrons on its outer shell. So NO4 would have a central Nitrogen atom, with 3 oxygens providing a single bond, and one oxygen providing a double bond, because Nitrogen needs 5 electrons!
We learned it like this, the atom brought x amount of electrons to the party, x representing the valence electrons, and must leave with x electrons. It's silly but it works!
I hope I was able to help and clarify a few things up!
