A covalent bond is formed between two atoms with similar electronegativity.
The electronegativities of it's two atoms are similar.
These atoms have a very similar electronegativity.
Atoms of any element are usually considered to be spherical in shape.
The electronegativities of it's two atoms are similar.
No.
It's possible but usually not. But any two regularones are definitely always similar.
The numbers of atoms with the same atomic number are the same in both reactants and products in any chemical reaction.
the two atoms must be of the same element
The electronegativities of two atoms are equal :)
A coordinate covalent bond forms when one atom contributes both electrons to the bond. When two similar atoms come together, they have similar electronegativities and electron affinities, making it difficult for one atom to donate both electrons to form a bond. As a result, a coordinate covalent bond is less likely to be formed between two similar atoms.
A nonpolar covalent bond is formed when electrons are shared equally between two atoms of similar electronegativity. This leads to a balanced distribution of charge and no separation of charges within the molecule.
