Question

Q 3) Answer the following question in one sentence following : 2 1) define Atomic radius 2) state Mendeleev’s periodic law ? 3) define Electropositivity​

Answer 1

Answer:

1.Atomic radius: The radius of an atom. This distance between an atom's nucleus and outer electron shell. 2.The Mendeleev's periodic law states that " The properties are a periodic function of their atomic mass." by using the atomic mass as the concept periodic classification of elements can be arranged in a groups.3.Electropositivity can be defined as the tendency of an atom to donate electrons and form positively charged cations. This property is primarily exhibited by metallic elements, especially the alkali metals and the alkaline earth metals. ... Electropositive elements often form ionic salts with electronegative elements.
