Question

The number of protons in an element X is 15 and the number of neutrons is 16 .What is the atomic no. and mass no. of that element respectively​

Answer 1

Answer:

​

X, where A stands for the atomic mass number which is the sum of protons and neutrons in the atom of an element and Z stands for an atomic number of the element which is the number of electrons in an atom of an element.

Atomic mass = Number of electrons + Number of neutrons

Atomic number = Number of protons = Number of electrons

Therefore, atomic mass =15+16=31 and atomic number is =15.

Explanation:

Answer 2

Answer:

element x is having 15 protons and 16 neutrons .

the atomic no. would be in the ratio of the protons and neutrons .

so , the atomic no. is 118.

the mass no. would be by doing addition in bedmas rule.

so , the mass no. is 244.

and the element would be 24rr63df21gt
