The atomic number of technetium (Tc) is 43.
The atomic weight of Tc is 98 grams per mole.
See the Web Links to the left of this answer for a periodic table with more information about this element!
If 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
The atomic number of Tc is 43 and its Atomic Mass is 98 for its most stable isotope. Tc-43 thus has 55 neutrons (98 - 43 = 55).
Technetium (Tc) has an atomic weight of 98.9063g/mol
The atomic number of technetium is 43; the atom is neutral.
43, as its atomic number is 43
Technetium has 43 protons.
43 97.9072
I assume you mean the atomic mass. Its atomic mass is 98.91g/mol
The atomic mass (not molecular weight) of technetium-99 is 98,906 254 7(21).
Technetium has the atomic number 43 but is an isotope with 99 protons
Titanium(Ti)

The atomic number of Technetium is 43.
Technetium has the symbol of Tc. It has the atomic number of 43.
Technetium was discovered in 1937 by Carlo Perrier and Emilio Segre. Technetium has the symbol Tc and the atomic number 43.
The atom with atomic number 43 is Technetium. One thing should be known. If looking at a periodic table this element doesn't have an atomic weight. This is because this atom has no stable isotope present and therefore an atomic weight cannot be calculated.
it is Tc.
Technetium has the atomic number 43 but is an isotope with 99 protons
Titanium(Ti)
Technetium which has an atomic mass of 98.
