Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period. Element Groups Elements in a group...

To determine whether element 'A' has a lesser or higher electron affinity than element 'B', we can follow these steps:Step 1: Understand the Position of Elements in Period 2 - In the periodic table, elements are arranged in per
level, the atomic radius grows as it moves down the group. Because adding an electron shell pulls the valence electrons further away from the nucleus, electronegativity falls as you move down a group. Thus in order to understand the trends and properties groups and period are of great ...
Calcium - 2,8,8,2 - Four shells are there, so period no. is 4. To determine the group, we need to understand some rules: 1. If the element is in s block, then the group number is equal to the number of valence electrons. ...
