All group 2 element have same outmost shell (2)
Draw the structure based on the name. Then count the number of times each atom appears in the structure. Alternately, you can determine the formula from the structure - and then count all atoms of each type.
The number of atoms in an element depends on WHAT element AND how much of that element.

Atomicity is having atoms. Also the number of atoms in a molecule.

The most abundant element in any organic structure, including the human is hydrogen.
Draw the structure based on the name. Then count the number of times each atom appears in the structure. Alternately, you can determine the formula from the structure - and then count all atoms of each type.
Symbols are used when showing the molecular structure of a substance, for example the molecular structure of water is H2O meaning that it has 2 hydrogen atoms (H) and 1 oxygen atoms (O)
The number of atoms in an element depends on WHAT element AND how much of that element.
It is an element or a compound, it belongs to the order of pure matter.
Correct: ''the atoms of the element X are isoelectronic with the ions of the element Y".
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
The molecular formula specifies the actual number of atoms of each element in a molecule.
