∙ 12y agoIf the Atom is not an ion, then:
# of electrons = # of protons = atomic number of Technetium (Tc)
Atomic Number of Tc is 43, hence the number of protons will also be 43.
If the Atom is an ion, then:
# of electrons =! # of protons (" =! " means: does not)
# of electrons = atomic number - Ionic Charge

What is the atomic mass of technetium?
I assume you mean the atomic mass. Its atomic mass is 98.91g/mol
What is the molecular weight of technetium 99?
The atomic mass (not molecular weight) of technetium-99 is 98,906 254 7(21).
How many protons and neutrons are in technetium -95?
Technetium has the atomic number 43 but is an isotope with 99 protons
What is an element with an atomic mass of 47.9?

Why is the atomic mass of technetium usually in brackets?
The brackets are used for isotopic elements--those with variable numbers of neutrons. The atomic weight of the most stable isotope is the one in brackets.
