All periods start with alkali metal and end with noble gases. 2. If we see table, it is very clear that from 1 s to 7 h period there is an addition of one shell in the each period like n=1,2,3,4,5. 3. Every new period is the start of addition of electrons in new shell. 4. Rows of elements are called periods.

The tendency of an atom in a molecule to attract the shared pair of electrons towards itself is known as electronegativity. It is a dimensionless property because it is only a tendency. The most commonly used scale to measure electronegativity was designed by Linus Pauling. The scale has been named the Pauling scale in his honour. According to this scale, fluorine is the most electron…
