The atoms of the elements in the same group have the same number of valence electrons. This means that they react with other elements in a similar way. For example group 1. All the atoms in group 1 react with water and oxygen, so they have to be kept in paraffin-oil. Another example is group 18. They don't react with anything. The atoms of the same row have the same electron shells.
Are they in the same row
Atoms whose symbols appear on a single row of a periodic table have the same number of electron shells. (Atoms with different numbers of protons represent different elements.)
The correct answer is: They all have the same number of core electrons.... chris ellis

they all have the same number of core electrons
they all have the same number of core electrons
They all have the same number of core electrons
The row is called the period. Each element in the same period has the outermost electrons in the same shell (energy level). For example, the elements in the 3rd period all have the outermost electrons in the 3rd shell.
1. An element contain only specific atoms of this element and no other atoms. 2. Compounds as calcium aluminates contain both aluminum and calcium.
the period
Elements that are in the same horizontal (left to right) rows, have similar outer shells.
