the basic aim of every atom is to be stable. to achieve this stability they either donate or accept electrons making ionic bond or share electrons so as to make a covalent bond. atoms form ionic bond only in case when one is cation and the other is anion(metal and non-metal reactions ), but in case of non-metal reacting with non-metal covalent bond is formed because non-metals because of their electronegative nature can't make cations and only share electrons.

An atom in a polar covalent bond that attracts electrons more strongly is said to have greater what?
Electronegativity ~ "a measure of n atom's ability to attract a shared pair of electrons within a covalent bond"
What kind of bond is between N and O electrons?
The bond between nitrogen and oxygen is always covalent. In some compounds there are double bonds.
What is Formal charge of the atom?
Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.
What type of bond is ionic and covalent bond?
IONIC BOND: The compound formed by completely transporting an electron or a number of electrons is called an ionic compound, and the bond between the elements of the compound is called the ionic bond. EXAMPLE: NaCl is an ionic compound in which the Na atom donates 1 electron to Cl atom to attain stability and thereby to form the compound NaCl. In ionic bond, generally the metals are the electron donors and the nonmetals are the electron acceptors COVALENT BOND: The bond formed by sharing pair(s) of electrons is called covalent bond. In this type of compound, each of the atom shares equal no. of electrons in order to attain stability. A covalent bond can be of three types: single covalent bond, where 1 pair of electrons is shared between the atoms; double covalent bonds, where 2 pairs of electrons are shared; and triple covalent bond, where 3 pairs of electrons are shared.EXAMPLE:N2 molecule is formed by sharing of 3 pairs of electrons, thereby forming a N-N triple bond
When two atoms combine by sharing electrons it is a(n) bond?
It is a covalent bond.
A chemical bond formed when two atoms share electrons is called a(n)?
a covalent bond is when two atoms share a pair of electrons
An atom in a polar covalent bond that attracts electrons more strongly is said to have greater what?
Electronegativity ~ "a measure of n atom's ability to attract a shared pair of electrons within a covalent bond"
What kind of bond is NH inNH3?
The bond between N and H in NH3 is a covalent bond, as electrons are shared.
What kind of bond is between N and O electrons?
The bond between nitrogen and oxygen is always covalent. In some compounds there are double bonds.

When two atoms combine by sharing electrons it is a(n)?
It is a covalent bond.
Is nitric oxide dative or 'normal' covalent bond?
Nitric oxide has a dative (coordinate) covalent bond. The N has donated both electrons and the O has also donated 2 electrons to make the N=O.
When two atoms combine by sharing electrons it is a(n) bond?
It is a covalent bond.
When two atoms combine by sharing electrons it is a(n) bond.?
It is a covalent bond.
When three pairs of electrons are shared what kind of covalent bond is formed?
carbon to carbon can make single, double or triple bonds. C2H2 which is acetylene (aka ethyne) has each carbon single bonded to hydrogen, and triple bonded to each other, 3 pairs of shared valence electrons = a triple covalent bond. Pure diatomic nitrogen also has this, with each having a pair of unshared electrons as well.
What happens when covalent compounds are mixed with water?
If the compounds are polar covalent then they are soluble in water . If they contain high electronegative element like F,O and N ,water can form inter molecular hydrogen bond with those compounds.
