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

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
