Question

How many protons neutrons and electrons are present in the 93Nb+3 ion

Answer 1

Answer:- The given ion has 41 protons, 52 neutrons and 38 electrons.

Solution:-  Atomic number for Nb is 41 and it's mass number is given as 93.

We know that, atomic number = number of protons

Since the atomic number is 41, it has 41 protons.

For a neutral atom, number of electrons = number of protons

Since the element has +3 charge, It must have lost three electrons to form the ion.

$Nb\rightarrow Nb^+^3+3e^-$

So, the number of electrons for the given ion = 41 - 3 = 38

number of neutrons = mass number - number of protons

number of neutrons = 93 - 41 = 52

So, the given ion has 41 protons, 52 neutrons and 38 electrons.
