what is the formula of a biavalent radical which consists of metal and non metal
Answers
Answer:
A chemical formula is a collection of atomic symbols with certain rules. For example, the formula for water is H2O and table salt (sodium chloride) is NaCl. The number of each atom in a chemical formula is written as an index number. In the water chemistry formula (H2O), the index number H is 2 and the index number O is 1 (the index number I does not need to be written). As for the chemical formula for table salt (NaCI), the index number for the two atoms is 1, so you don't need to write it down. The chemical formula of a substance is typical. The peculiarity is determined by the binding power and oxidation number of an atom. Atomic binding power is the ability of an atom to bind other atoms to form a molecule. The bonding power of atoms is also called valence. Each atom has a certain binding power.
To understand the binding power of atoms, consider the compounds HCI, H2O, NH3, SO2, SO3, and CH. In fact, Cl binds 1 H atom, O binds 2 H atoms, N binds 3 H atoms, S binds 2 or 3 O atoms, and C binds 4 H atoms, because it has the smallest binding power, the H atom is used as a comparison and is determined to have a valence 1. Therefore, the atomic valence of CI is 1, the valence of the atom of O is 2, the valence of the N atom is 3, the valence of the atom of S is 4 or 6, and the valence of the atom of C is 4.
Binary compounds are chemistry that is made up of only two elements. The elements formed can consist of metal and non-metal elements or both of them consist of non-metal elements
1. CHEMICAL FORMULATION
a. Atomic Binding
b. Binary Compound Nomenclature
If the binary compound consists of metallic and non-metallic elements, the rules for naming the compounds are as follows.
The names of metallic elements are mentioned first, followed by the names of non-metallic elements ending in -ide.
Example:
NaCl = Sodium chloride MgBr2 = Magnesium bromide
Na is a metal element Mg is a metal element
Cl is a nonmetal element Br is a nonmetal element
Although ionic compounds are composed of positive and negative ions, they are neutral overall, so their total charge is zero. This means that one Na + will combine with one Cl - in NaCl and one Mg2 + combine with two Br - in MgBr2 and so on. Here is an example of giving simple compound names and symbols:
