Some isotopes of elements are unstable and decay into other, more stable isotopes over time. for example, it takes 153 years for half of a sample of silicon (si) atoms with 14 protons, 14 electrons, and 18 neutrons to decay. what is the name of this specific silicon isotope?

Silicon-32

Explanation:

Silicon-32 is the isotope of silicon. It's half life is 153 years. It means that it takes 153 years to decay for half of a sample of Silicon atom which has 14 proton, 14 electron and 18 neutrons.

So, answer is Silicon-32.

The name of an isotope will be Silicon-32

Explanation:

Isotopes are those chemical variants of same elements with same number electrons and protons. But differ in number neutrons.

Name of the silicon isotope with:

14 number of protons

14 number of electrons

18 number of neutrons.

Atomic mass of an atom is concentrated in its nucleus which contains protons and neutrons.

Mass of silicon isotope= Number of neutrons+ number of protons

18 + 14 = 32 amu

The name of an isotope will be Silicon-32
