How many valence electrons are there in a molecule of crotononitrile?
A molecule of crotononitrile (C4H5N) has 9 valence electrons. This is calculated by adding the valence electrons of each element: carbon (4), hydrogen (5), and nitrogen (1).
Based on the number of valence electrons what is the correct formula when nitrogen bonds with hydrogen?
Nitrogen has five valence electrons, while hydrogen has one valence electron. To achieve a stable configuration, nitrogen typically forms three bonds with hydrogen atoms, utilizing three of its valence electrons. Therefore, the correct formula when nitrogen bonds with hydrogen is NH₃, or ammonia.
What is a molecule that the valence electrons are shared equally between the two atoms?
a non polar covalent molecule
What do shells (energy levels) and valence electrons have to do with atoms combining to make molecules?
Valence electrons form the bonds between atoms in a molecule.
How do the atoms gain stable outer shells in ammonia?
In ammonia (NH₃), nitrogen has five valence electrons and needs three more to achieve a stable outer shell, while each hydrogen atom has one valence electron. The nitrogen atom shares its three valence electrons with three hydrogen atoms, forming three covalent bonds. This sharing allows nitrogen to attain a full outer shell with eight electrons (including the shared ones), while each hydrogen achieves a stable configuration with two electrons through the shared bonding. Thus, all atoms in ammonia gain stable outer shells through these covalent interactions.
What is the number of valence electrons in a molecule of ammonia?
A molecule of ammonia (NH3) has 8 valence electrons - 5 from nitrogen and 1 each from the three hydrogen atoms.
What is the valence of oxygen and hydrogen in a water molecule?
Oxygen has a valence of 2 in a water molecule, while hydrogen has a valence of 1. This allows for the formation of two covalent bonds between the oxygen and the two hydrogen atoms in water (H2O).
How many lone pairs of electrons persent in a molecule of ammonia?
There is one lone pair of electrons in a molecule of ammonia: The single nitrogen atom in the molecule has five valence electrons; one of these is in a covalent bond with each of the three hydrogen atoms; and the remaining two valence electrons from the nitrogen atom constitute a lone pair.
Is NH3 covalent or ionic bond?
An ammonia molecule has covalent bonds in it.
How many valence electrons does ammonia have?
Ammonia (NH3) has 8 valence electrons. Nitrogen contributes 5 valence electrons and each hydrogen contributes 1 valence electron.
How many valence electrons in H2 atom?
H2 is not an atom, it is a diatomic molecule. Each hydrogen atom has 1 valence electron. When two hydrogen atoms covalently bond to form an H2 molecule, there are two valence electrons being shared by the two atoms.
How many pairs of valence electrons are there on the oxygen atom in the water molecule?
There are 4 valence electrons on the oxygen atom in the water molecule. Oxygen has 6 valence electrons, and in a water molecule, oxygen forms 2 covalent bonds with the hydrogen atoms, sharing 2 of its valence electrons with each hydrogen atom.

Is the correct Lewis structure for ammonia (NH3) Note Hydrogen and nitrogen have one and five valence electrons respectively.?
Yes, the correct Lewis structure for ammonia (NH3) shows nitrogen with a lone pair of electrons and three single bonds, each connecting a hydrogen atom to nitrogen. This arrangement satisfies the octet rule for each atom involved in the molecule.
How many hydrogen atoms are necessary to join with nitrogen atoms to form a stable compound?
Three. Think of NH3 , ammonia. Nitrogen has a valence of three, Hydrogen's is one.
How many valence electrons if oxygen and hydrogen combine?
When oxygen and hydrogen combine to form water (H2O), oxygen contributes 6 valence electrons (group 16, 6 electrons) and each hydrogen atom contributes 1 valence electron (group 1, 1 electron), resulting in a total of 8 valence electrons in the water molecule.
