Question

What percentage metals metalloids and nonmetals are there within the playing period of the periodic table?

Answer 1

Hint: A metalloid is a component that has properties that are intermediate between those of metals and nonmetals. Metalloids also can be called semimetals. On the table , the weather colored yellow, which generally border the stair-step line, are considered to be metalloids.

Complete answer:
The playing period contains eight elements: sodium (Na), magnesium (Mg), aluminium (Al), silicon (Si), phosphorus (P), sulfur (S), chlorine (Cl), and argon (Ar).
Among all of these, there are three metals (sodium, magnesium, aluminium), four are nonmetals (phosphorus, sulfur, chlorine, argon) and one is metalloid (silicon). However, argon is the inert gas.
There are 110 elements known to us, out of which 92 are present, while the remainder is prepared artificially. Elements are then classified into the metals, non-metals, and metalloids.
The playing period contains only eight elements albeit the electron capacity of the third shell is eighteen because when the opposite shells get filled and therefore the resultant number of electrons becomes eighteen, it gets added up and settles within the third group and three shells are acquired by the fourth period.
Scandium is element number 21 on the table. Its symbol is Sc. Scandium may be a metal during a group referred to as the transition metals.

Note:
Argon, chlorine, sulfur and phosphorus are non-metals. On the left side of period 3 we discover the weather sodium, magnesium and aluminium. The more electrons a metal can contribute to the chemical bond the more mobile electrons there'll be and therefore the stronger the chemical bond.
