Mean by Prediction of Group, Period and Block of an Element –
(i) If the element is in s block, then the group number is equal to the number of valence electrons.
(ii) The period of an element corresponds to the principal quantum number of the valence shell.
(iii) If the element is in the p block, then the number of the group can be determined by the formula.
(iv) Principal quantum number of the valence shell corresponds to the period of an element.
(v) The orbital containing the last electron indicates the block of an element.
