Question

What are normal elements?

Answer 1

Hint: In chemistry an element is a solid, organic product, composed of atoms with the same protons in their atomic nuclei and which cannot be broken down by any kind of chemical means. There were a total of 118 elements identified. The first 94 exist on Earth, and the other 24 are synthetic elements that are produced in nuclear reactions. Save for unstable (radionuclides), rapidly decaying radioactive elements that almost all elements are industrially available in varying quantities.

Step-By-Step answer:
Family of halogen components: Class 17—fluorine (F), chlorine (Cl), bromide (Br), iodine (I), and astatine (At) items. The general electronic configuration is $ns^2np^5$. Normal elements are basically elements of the s and p-block, named as normal elements or main group elements in the periodic table.
The halogen group is the only periodic table group of elements at normal temperature and pressure in three big states of matter. When tied with hydrogen, all halogens form acids. The majority of halogens are generated by minerals or salts. Halogens from the centre – chlorine, bromine and iodine – are widely used as disinfectants. Halogens are highly reactive, and in sufficient quantities can be dangerous or lethal to biological organisms. The strong reactivity in atoms is because of the heavy electronegativity of the nuclear charges. Since halogens have seven valence electrons in their outermost energy level, they can react with other elements' atoms to satisfy the octet rule.

Note: The high fluorine reactivity paradoxically makes some of the strongest potential bonds, in particular, with carbon. Teflon, for example, is carbon bonded tightly with fluorine, highly resistant to thermal and chemical attacks and has a high melting point.
