Question

Identify the correct atomic structure of the Al³⁺ ion where n and p represent the number of neutrons and protons respectively.

How many protons, electrons, and neutrons are present in X⁻ if the atomic number of X is 17 and the mass number is 35?

The number of electrons in an element X is 15 and the number of neutrons is 16. Which of the following is the correct representation of the element?

Which of the following are true for an element? (i) Atomic number = number of protons + number of electrons (ii) Mass number = number of protons + number of neutrons (iii) Atomic mass = number of protons = number of neutrons (iv) Atomic number = number of protons = number of electrons

What information do you get from the Fig. 4.4 about the atomic number, mass number and valency of atoms X, Y and Z? Give your answer in a tabular form.
