Question

Hey guys answer fast ....​

Answer 1

Periodicity of properties : It is the recurring interval in which the properties of an element are found to be similar or in other words repeat.

Electron affinity: It is the likelihood of an element gaining an electron

Modern Periodic Law: It states that the properties of an element are a periodic function of its atomic number

Answer 2

▪︎Periodicity refers to trends or recurring variations in element properties with increasing atomic number. Periodicity is caused by regular and predictable variations in element atomic structure. ... Elements within a group (column) display similar characteristics.

▪︎The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.

▪︎The modern periodic law states that the properties of the elements are a periodic function of their atomic numbers. ... There are 18 groups and 7 periods in the modern periodic table. s-block - the highest energy electron fills the s orbital. p-block - the highest energy electron fills the p orbital.
