an element in period 2 which has the same atomicity as hydrogen
Dear student,
Atomicity is the total number of atoms that constitute a molecule. Like hydrogen is composed of two atoms so its atomicity is 2.
The elements in the period 2 are Lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon.
Atomicity of hydrogen is 2. The elements in period 2 having atomicity 2 i.e. same as that of hydrogen are nitrogen, oxygen and fluorine. This means these are present as H2, N2, O2 and F2.
