Q34.
1. the properties of an element have periodic dependence upon its atomic number and not on relative atomic mass
2. Hydrogen can also gain an electron to achieve a noble gas arrangement and hence it can behave similar to a group 17 (halogen family) elements
3. the number of elements in each period is twice the number of atomic orbitals available in the energy level that is being filled
