Question

What atoms have $5$ protons?

Answer 1

Hint: The atom is the smallest unit of matter consisting of three subatomic particles: the proton, the neuron and the electron.
The atomic number(Z) of an element tells us the number of protons in one atom of an element.

Complete answer:
The number of protons in an atom is referred to as atomic number (Z). The Atomic number is unique for the atoms of a certain element.
The only atom which has $5$ protons is Boron.
Boron’s atomic number is$5$. This tells us that an atom of Boron has $5$ protons in its nucleus. It basically belongs to Group $13$. Group $13$ comes under the p-block. It is a non-metallic element.
The Electronic Configuration of Boron is: $1{{s}^{2}}2{{s}^{2}}2{{p}^{1}}$
Boron’s normal phase is solid which means it is solid at room temperature. It belongs to the Metalloids family. Metalloids are elements which have properties that are intermediate between those of metals and nonmetals.
Boron having the symbol B is a chemical compound having atomic number $5$.
No. of Protons in Boron = $5$
No. of Neutrons in Boron =$4$
No. of Electrons in an uncharged Boron atom = $5$
Atomic number(Z) of Boron = $5$
Mass Number(A) –>$10.81$ Approx. $11$(Mass Number is basically the number of protons and the number of neutrons combined.)
Period and Group of Boron = ${{2}^{nd}}$ period and ${{13}^{th}}$ group
Common Compounds of Boron:
Boric Acid - $B{{(OH)}_{3}}$
Boron Carbide - ${{B}_{4}}C$
Boron Nitride - $BN$
Boron Tribromide - $BB{{r}_{3}}$
Boron Trichloride - $BC{{l}_{3}}$
Boron Trifluoride - $B{{F}_{3}}$
Boron Trioxide - ${{B}_{2}}{{O}_{3}}$

Note:
For any element:
Number of Protons = Atomic Number
Number of Electrons = Number of Protons = Atomic Number
Number of Neutrons = Mass Number - Atomic Number
