The period number helps in determining the number of shells in the element. For example, Sodium (Na) is in 3rd period that means there are 3 shells in the atom of an Sodium.
The periodic table table has elements arranged in increasing order of the atomic number. NaCl is a salt derived from sodium and chloride ions. Neither ions nor compounds are listed in periodic table. The elements involved in producing the salt are sodium (period 3 group 1) and chlorine (period 3 group 17).NaCl is made up of two elements: sodium and chlorine. Sodium is present in group-1. Chlorine is present in group-17.
sodium(Na) belongs to the Ist group. This group is also known as alkaline metals.
Magnesium's group number is 2. Its period number is 3.
The group no. of Lithium is 1 and its period number is 2.
Sodium is an Alkali Metal, this is group 1 in the periodic table.
In the older versions of the periodic table, group VIIA corresponds to the current group 17, the halogens.
Sodium is atom number 11, 3rd period, 1st group, Chlorine is atom number 17, 3rd period, 17th (or 7th) group.
Sodium, potassium and rubidium are in the first group of the periodic table. Sodium is in the period 3. Potassium is in the period 4. Rubidium is in the period 5.
Sodium is found in Group 1, also known as the Alkali metals or Lithium family, Period 3, with an atomic number of 11 and is represented by the symbol "Na".
The period number helps in determining the number of shells in the element. For example, Sodium (Na) is in 3rd period that means there are 3 shells in the atom of an Sodium.
group 1 period 3
Sodium is an alkali metal, placed in period 3, group 1 of the periodic table of Mendeleev; the atomic number is 11.
