The answer is: The electronic configuration of Nitrogen is
.
Electronic configuration: The electronic configuration is defined as the distribution of electrons of an atom in the atomic or molecular orbitals and is written using the labels for the subshell.
How to decide which orbital is filled first?
- The order in which electrons are filled in atomic orbitals as:
(Shown in image)
- Just follow the arrows to select the orbitals, s orbital can have 2 electrons, p can have 6 electrons, d can have 10 electrons and f can 14 electrons.
- The electronic configuration in which the outer shell is completely filled is known as noble-gas configuration as they are similar to electronic configurations of noble gases.
- Now, the given element is nitrogen (
). The atomic number of Nitrogen is 7. Thus, these 7 electrons are filled as-
![1s^22s^22p^3](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E3)
- Therefore, the electronic configuration of Nitrogen is
.

Answer:
A. the bond's yield to maturity is equal to its coupon rate.
Explanation:
The coupon rate is that amount of bond measured on the loan amount whereas the maturity yield is the rate held up to the settlement date and the investment arise up to the maturity date.
Since the bond is currently trading at its face value that means the bond price is equal to the face or par value
So, the appropriate option is A.
The increase in pressure alters the equilibrium of the reaction. In this case, the number of gaseous products in the reactant side is zero while the product side contains 1 gaseous product. The increase in pressure favors the side with less number of gaseous molecules which is the reactant side. Hence, the reaction rate decreases.
β⁻ emission is an emission of an electron by converting a neutron
to a proton. Hence, in β⁻<span> decay, the atomic
number of daughter atom increases by 1 than the parent atom and
mass number is not changed in the formed daughter nucleus.</span>
Hence, formed daughter atom should have 89 + 1 = 90 as atomic number. Hence, the daughter atom should be Th (<span>Thorium)</span>
<span>The equation is</span>
₈₉²²⁸Ac → ₉₀²²⁸Th + ₋₁⁰β + energy<span>

It is a single replacement
because your doing a single replacement between 2AL and 3Ni
<span>2Al + 3NiBr2------> 2AlBr3 + 3Ni
