YES

The ammonia molecule has a trigonal pyramidal shape with a bond angle of 107.8°, as predicted by the valence shell electron pair repulsion theory (VSEPR theory). The central nitrogen atom has five outer electrons with an additional electron from each hydrogen atom. This gives a total of eight electrons, or four electron pairs that are arranged tetrahedrally. Three of these electron pairs are used as bond pairs, which leaves one lone pair of electrons. The lone pair of electrons repel more strongly than bond pairs, therefore the bond angle is not 109.5°, as expected for a regular tetrahedral arrangement, but is measured at 107.8°.

What is name of compound NH?

A compound made up of hydrogen and nitrogen, for example ammonia (NH3).


Are non polar covalents created when the shared electrons between atoms are not equally shared?

Yes, nonpolar covalent bonds are formed when the shared electrons between atoms are shared equally, resulting in a balanced distribution of electric charge. If the shared electrons are not equally shared, creating an unequal distribution of charge, a polar covalent bond is formed.


Are the shared electrons in a covalent bond always shared equally between two atoms?

No, in a covalent bond the shared electrons may not always be shared equally between two atoms. Depending on the electronegativity of the atoms involved, one atom may attract the shared electrons more strongly, leading to a polar covalent bond where the electrons are not shared equally.

Is a covalent bond considered polar if the two atoms share the electrons equally?

No, a covalent bond is considered nonpolar when the two atoms share the electrons equally. If the electrons are not shared equally and there is an unequal distribution of charge, then the bond is considered polar.

A bond in which electrons are shared equally is?

Called a covalent bond.


A covalent bond is considered if the two atoms share the electron equally?

no. A polar bond is a covalent bond in which electrons are shared unequally. A nonpolar bond is a covalent bond in which electrons are shared equally.


What is a bond called in which electrons are shared equally?

a non-polar bond


What determines whether electrons are shared equally or non equally in a covalent bond?

It depends on the electronegativity of the atoms in the molecule. When an atom has a higher electronegativity than the others in the molecule, the electrons will have a higher affinity for that side, making the molecule polar.


What is covalent bond called in which electrons are shared equally?

A covalent bond in which electrons are shared equally is called a nonpolar covalent bond. This means that the atoms have the same or similar electronegativities, resulting in a balanced sharing of electrons between them.
