If the number of electrons in a neutral atom is 6 and the number of neutrons is 8. Then the atomic mass of that element will be ___.

Q. If the number of electrons in a neutral atom is 6 and the number of neutrons is 8. Then the mass number of that element will be ___.

Q. The atomic composition of element A is as follows: number of neutrons = x, atomic mass = 12, number of electrons = 6. The atomic composition of B is as follows: number of neutrons = y, atomic mass = 28, number of electrons = number of electrons in A + 8.
The ratio of x to y is:

Q.

An element ‘X’ has mass number = 27. If the no. of electrons is given as 13, the no. of neutrons will be ___ .

(Assume that atom is neutral)

Q. What is the atomic number of an element with 6 electrons and 8 neutrons?

Q.

Which of the following statements is/ are correct about neutral elements?

(i) Atomic number = number of protons = number of electrons
(ii) Mass number = number of protons + number of neutrons
(iii) Atomic number = number of protons + number of electrons
(iv) Mass number = number of neutrons = number of electrons
