Question

Hat is the atomic number for the following elements? C I Li O N Rb

Answer 1

C : 6

Carbon is a chemical element with the symbol C. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.

I : 53

Iodine is a chemical element with symbol I .It is heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.

Li : 3

Lithium is a chemical element with the symbol Li .It is a soft, silvery-white alkali metal.Lithium is used to treat mania that is part of bipolar disorder (manic-depressive illness). It is also used on a daily basis to reduce the frequency and severity of manic episodes

O : 8

Oxygen is the chemical element with the symbol O. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.

N : 7

Nitrogen is the chemical element with the symbol N. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. 

Rb : 37

Rubidium is the chemical element with the symbol Rb. It is a very soft, silvery-white metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity.It cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the metal catching fire
