➡WHAT DO U MEAN BY PERIODICITY?

In the context of chemistry and the periodic table, 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.

➡WHAT IS CATENATION? In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. A chain or a ring shape may be open if its ends are not bonded to each other, or closed if they are bonded in a ring. The words to catenate and catenation reflect the Latin root catena, "chain"

➡WHAT DO U MEAN BY ROASTING?

To roast can mean to cook, or to poke fun of someone as a way of honoring them. In cooking, slow, dry heat is used to roast things. When a cook roasts a piece of meat, you can call the meat itself a roast too. Another way to use this word is to mean “to make fun of someone,” like a toast but meaner and funnier.

Answer 2

Explanation:

• Repetition of properties after a certain interval is called periodicity of properties. If elements are arranged in increasing order of their atomic number in the periodic table, then elements repeat its properties after a definite interval. This repetition of properties is known as periodicity of properties.

• Catenation : The self linkage is known as catenation. The property of catenation is responsible for the occurrence of innumerable oragnic compounds. It is the binding of an element to itself through covalent bonds to form chain or ring molecules.
