In 1st excited state of P have 5 unpaired electron. So it can form 5 covalent bonds. Nitrogen is a diatomic molecule in the VA family on the periodic table.
How many covalent bonds are predicted for phosphorus?
This element has 3 valence electrons. It will form (8 – 3) = 5 covalent bonds.
At what temperature do covalent bonds break?
All Answers (1) Normally at 100 degrees centigrade the hydrogen bond breaks.
Is a hydrogen bond?
Hydrogen Bonding. Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
Which covalent bonds are the longest?
Single bonds are the longest of the three types of covalent bonds as interatomic attraction is greater in the two other types, double and triple. The increase in component bonds is the reason for this attraction increase as more electrons are shared between the bonded atoms (Moore, Stanitski, and Jurs 343).
How many covalent bonds are predicted for chlorine?
In these compounds carbon, nitrogen, oxygen, and chlorine atoms have four, three, two, and one bonds, respectively. The hydrogen atom and the halogen atoms form only one covalent bond to other atoms in most stable neutral compounds.
How many covalent bonds are predicted for B?
How many covalent bonds are predicted for B? B has three valence electrons, it is expected to form three bonds.
Can hydrogen form a covalent bond?
Hydrogen can participate in both ionic and covalent bonding. When participating in covalent bonding, hydrogen only needs two electrons to have a full valence shell. As it has only one electron to start with, it can only make one bond.
