coefficients
subscript
The elements that are placed outside of the periodic table are called transactinides. These elements are usually placed in a separate row below the main table and are synthetic elements that do not occur naturally on Earth.
Elements between 57 and 70 belongs to the f group. Elements from La - Lu belongs to this group. These are called Lanthanides.These elements are Lanthanides. They are placed separately. They have different chemical properties.
more electropositive element first, followed by electronegative elements
That is called a coefficient in a chemical equation. It indicates the number of molecules or units of a substance involved in a reaction.
subscript
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
The number placed in front of a chemical symbol or formula is called a coefficient. It represents the number of molecules or formula units in a chemical reaction.

The elements that have been removed from period 7 and placed below the periodic table are called the "lanthanides" and "actinides". These elements are also known as the "rare earth elements" and they are placed separately to conserve space on the periodic table.
more electropositive element first, followed by electronegative elements
The number placed in front of a chemical formula in a chemical equation is called a coefficient. Coefficients are used to balance chemical equations by ensuring that the number of atoms of each element is the same on both sides of the equation.
That is called a coefficient in a chemical equation. It indicates the number of molecules or units of a substance involved in a reaction.
The ratio of different elements present in a compound can be determined using the subscripts or coefficients in a chemical formula. These coefficients represent the relative number of each type of atom in the compound.
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
The number placed below an element symbol in a chemical formula is called a subscript because it indicates the number of atoms of that element in a molecule or compound. The subscript is written slightly below the element symbol to differentiate it from the coefficient, which applies to the whole molecule or compound.
