Answer:
Explanation:
First, let's define <u>atomic number</u>.
⇒ The number of <u>protons </u>in an atom.
⇒ This number determines the identity and properties of the atom
So, atomic number relates to protons. There is an increase in atomic number, so there must be <u>more</u> protons in the atom. We can eliminate choices A and B, because they pertain to electrons.
We are left with choices C and D. The difference between them is the location of the protons.
Protons are part of the <u>nucleus </u>of the atom: the dense, central region of the atom comprised of nucleons: protons and neutrons.
Electrons, not protons, orbit the nucleus, so D is not correct.
We are left with choice C: <u>more protons are present in the atomic nucleus </u>

Nitrifying Bacteria are a group of aerobic bacteria important in the nitrogen cycle as converters of soil ammonia to nitrates, compounds usable by plants. An example is nitrosomonas or nitrobacter and species in that family.
The schematic diagram is attached below, which summarises the oxidation of ammonia or free nitrogen in the soil to nitrates for the cowpea plant's utilisation.
Answer:
Here's what I get.
Explanation:
The MO diagrams of KrBr, XeCl, and XeBr are shown below.
They are similar, except for the numbering of the valence shell orbitals.
Also, I have drawn the s and p orbitals at the same energy levels for both atoms in the compounds. That is obviously not the case.
However, the MO diagrams are approximately correct.
The ground state electron configuration of KrF is
KrF⁺ will have one less electron than KrF.
You remove the antibonding electron from the highest energy orbital, so the bond order increases.
The KrF bond will be stronger.
