If technetium-98 has 55 neutrons how many does technetium-99 have?

Answer 1

Tc has 55 neutrons, its variants such as Tc-99 have a differing number of neutrons ranging from 54, 55, and 56 in the longer lived isotopes such as Tc-99. Tc-99 also has a half-life of 211,000 years.

Answer 2

Technetium has atomic number 43 so has 43 protons. The rest of the mass is neutrons so do 95 takeaway 43.

Answer 3

Technetium-99 would have 56 neutrons, as the atomic number increases by 1 to match the increase in neutron number.

Answer 4

Technetium-97 has 54 neutrons.

Answer 5

56 neutrons
