Question

Define periodicity? Write the periodic properties, and explain how does the electro negativity of an element vary in period and groups? What are the factors which influence electro negativity?

Answer 1

Answer:

• Definition of 'periodicity'
• Definition of 'periodicity'1. the tendency, quality, or fact of recurring at regular intervals. 2. Chemistry. the occurrence of similar properties in elements occupying similar positions in the periodic table.
• On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.
• An atom's electronegativity is affected by both its atomic number and the size of the atom. The higher its electronegativity, the more an element attracts electrons. The opposite of electronegativity is electropositivity, which is a measure of an element's ability to donate electrons.
