Question

Write the name and symbol of the element from the description.
The most electronegative atom.

Answer 1

Hint: Periodic table is the representation of chemical elements arranged in the increasing order of atomic numbers. These all-chemical elements are arranged in the vertical columns and horizontal rows. The halogens are the non-metals and mostly have high electronegative atoms. Fluorine is the most electronegative atom in the periodic table.

Complete answer:
Chemical elements are the purest form of atoms and combine to form chemical compounds. There are a total of \[118\] elements arranged in the increasing order of atomic numbers in the periodic table. These elements are arranged in the vertical columns and horizontal rows. The vertical columns were known as groups and the horizontal rows were known as periods. There are \[18\] groups and \[7\] periods. The elements belong to the group \[17\] are known as halogens. These halogens exist as non-metals and exist as electronegative elements.
Fluorine, chlorine, bromine, iodine and astatine belong to halogens. Fluorine is the most electronegative element in the periodic table with the symbol of F and has the atomic number of \[9\]
The name and symbol of the element from the description of the most electronegative atom is fluorine and the symbol will be F.

Note:
Electronegativity is defined as the tendency of attraction of a shared pair of electrons towards itself. The halogens are the elements that are only one electron deficient to the nearest noble gas element. Thus, these elements attract electrons towards themselves from the other elements.
