Question

14 6R and 15 7R are the symbol of two elements. They are
(1) Isotopes
(2) Isotones
(3) Isobars
(4) Isoelectronic

Answer 1

iso electronic.......

Answer 2

Answer:

The correct answer is: isotones

Explanation:

Both the elements have same number of neutrons therefore they are isotones. Both have different number of electron,proton.

The number of neutrons can be calculated by difference between mass number and atomic number.

Number of neutrons=Mass number-atomic number

Here, given elements have:

Nunber of neutrons=14-6=8

Number of neutrons=15-7=8

Both the elements have same number of neutrons.

The elements having the same number of neutrons are known as isotones.

The both elements have different number of electron and proton but same number of neutrons.

Isotones have various applications.

Atomic number is denoted by A

Mass number is denoted by Z.

So,the elements having same A-Z value are called isotones.
