The three steps or formation of ionic compounds strontium and oxygen
Explanation:
Chemical bond
It is the linkage between two or more atoms in a molecule.
Cause of bond formation
The atoms combine with one another to achieve noble gas configuration. By doing so they become stable.
Atom can achieve noble gas configuration
By loosing one or more e’s.
By gaining one or more e’s.
By sharing one or more e’s.
Types of CHEMICAL BONDS
IONIC BOND (or electrovalent)
COVALENT BOND
Ionic bond
It is the Bond formed by transfer of electrons from one atoms to another.
It is formed when one atom donate electron & other accept electrons to achieve stable confugration.
NOTE: it is always formed between metal a non-metal.
Examples :-
* Formation of sod. Chloride as we know their atomic no., are
Na Cl
11 17 (atomic numbers of combining atoms )
. 2, 8, (1) 2, 8, (7) (Electronic configuration )
Metal non-metal (bond will be ionic)
We’ll start with metal
Na - 1 e- → Na+
Cl + 1e- → Cl-
Na + Cl → Na⁺ Cl⁻

NaCl
Similarly ,for strontium and oxygen
Sr ⁸⁺ O⁸⁻
x
SrO(Strontium oxide )
