What is the bond order of c2−?express the bond order numerically?
diamong [38]
MO Diagram of C₂⁻ is shown below, 

Bond order is calculated as,

             Bond Order  =  [# of e⁻s in BMO]-[#of e⁻s in ABMO] / 2
Where,

BMO  = Bonding Molecular Orbital

ABMO  =  Anti-Bonding Molecular Orbital

Putting values,

             Bond Order  =  [9]-[4] / 2

             Bond Order  =  5 / 2

             Bond Order  =  2.5

C. If the proton number increases while the number of energy levels remains constant,
Vladimir79 [104]

It increases

The attractive force between the nucleus and the electrons INCREASES if the proton number increases while the number of energy levels remains constant.

Explanation:

Remember that protons carry a positive charge while electrons carry a negative charges. Unlike charges attract while like charges repel. An increase in the number of protons increases the positive charge of the atomic nucleus. This means that the force of attraction on the electron cloud of the atom increases.

This is why the atomic radius of atoms decreases across a period (from left to right) as the mass number of the atoms increase (while the number of electron orbitals remains the same across the period).

How many lone pairs are around the central atom in the Lewis formula for the
barxatty [35]

Answer:

The answer to your question is None, sulfur share of its electrons

Explanation:

Just remember:

Sulfur, S, has 6 electrons in its outermost shell

Hydrogen, H, has 1 electron in its outermost shell

Oxygen, O, has 6 electrons in its outermost shell

See the picture below

The electrons of sulfur are in blue

The electrons of oxygen are in red

The electron in hydrogen is in yellow

Sulfur is the central atom and it shares all its electrons with the oxygen.
