Answer: N (atomic number 7)
Explanation:
1) Due the electron distribution of each, taking into account Hund's rule to deal with pairing of electrons.
2) Hund's rule: each subshell orbital is occupied with single electrons of parallel spin before double occupation occurs.
That is, before any one orbital is doubly occupied, every orbital in a subshell is singly occupied with one electron, and all the electrons in singly occupied orbitals have the same spin, which means that they are unpaired.
3) Distributions:
a) C (atomic number 6) ⇒ 6 electrons:
⇒ 1s² 2s² 2p² ⇒ 1s² 2s² 2p ↑ ↑ : as per Hund's rule the two electrons on 2p are unpaired.
b) O (atomic number 8) ⇒ 8 electrons
⇒ 1s² 2s² 2p⁴ ⇒ 1s² 2s² 2p⇅ ↑ ↑: as per Hund's rule the two 2p electrons are unpaired
c) N (atomic number 7) ⇒ 7 electrons
1s² 2s² 2p³ ⇒ 1s² 2s² 2p↑ ↑ ↑: as per Hund's rule, the three 2p electrons are unpaired, so this is the answer to the question.
c) Be (atomic number 4) ⇒ 4 electrons
⇒ 1s² 2s² ⇒ none p electron.
Nitrogen has three unpaired electrons in its p orbital.
Among the given elements, nitrogen (atomic number 7) has three unpaired electrons in its p orbital.
In the electron configuration of nitrogen, it has a total of five electrons: 2 in the 1st energy level and 3 in the 2nd energy level. The p sublevel of the 2nd energy level contains three orbitals, each capable of holding 2 electrons. Therefore, the three unpaired electrons in nitrogen's p orbital are in three separate p orbitals in the 2nd energy level.
Carbon has two unpaired electrons in its p orbital, while oxygen has two unpaired electrons in its p orbital and two in its s orbital. Beryllium does not have any unpaired electrons in its p orbital.

Any type of metal may join with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.
A chemical compound known as an ionic compound is one that contains ions bound together by the electrostatic forces known as ionic bonding. Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.
In most cases, ionic compounds are created between metal and nonmetal components. For instance, the ionic compound calcium chloride is made up of the metal calcium (Ca) and the nonmetal chlorine (Cl) (CaCl2).
A nonmetal and a metal can create an ionic bond, which is the attraction between two ions with opposing charges.
Thus, metal are joined with a non-metal, such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium, to create ionic compounds.

Ionic compounds are formed when any type of metal is combined with a non-metal such as carbon, nitrogen, oxygen, sulfur, phosphorus, and selenium.
(any)metal + nonmetal = ionic compound
An electric motor is a machine that is responsible for conversion of electricalenergy to mechanical energy. On the other hand a galvanometer is an electrical tool that is used to measures small values of current.
A galvanometer actually works by deflecting a pointer in an electric current response which is flowing through a coil under a constant magnetic field.
While an electric motor performs its operation through the interaction between the magneticfield of motor and electriccurrent in a wire winding which generate a force in the form of torque.
Thus, this was the difference between a galvanometer and an electricmotor.
