Answer & Explanation:
Subatomic particles are particles much smaller than atoms.
Atoms are composed mainly of protons, neutrons, and electrons.
³²P:
- number of electrons: 15,
- number of protons: 15,
- number of neutrons: 17.
³¹P:
- number of electrons: 15,
- number of protons: 15,
- number of neutrons: 16.
Answer: Thus for [tex]_{15}^{32}\textrm{P}[/tex] , no of electrons = no of protons = 15, number of neutrons = 17
For [tex]_{15}^{31}\textrm{P}[/tex] , no of electrons = no of protons = 15, number of neutrons = 16.
Explanation:
Isotopes are elements which have same atomic number but different mass number.
General representation of an element is given as: [tex]_Z^A\textrm{X}[/tex]
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element
Thus the isotopes of phosphorous are represented as [tex]_{15}^{32}\textrm{P}[/tex] and [tex]_{15}^{31}\textrm{P}[/tex]
An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons.
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
Atomic number = Number of electrons = Number of protons
Thus for [tex]_{15}^{32}\textrm{P}[/tex] , no of electrons = no of protons = 15 and number of neutrons = 32-15= 17.
Thus for [tex]_{15}^{31}\textrm{P}[/tex] , no of electrons = no of protons = 15 and number of neutrons = 31-15= 16.
