Which are inner transitional metals?
The inner transition metals are a section that has been pulled out of the periodic table. These elements are called Lanthanides (La) & Actinides (Ac). Lanthanides: Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb & Lu Actinides: Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Pu, and Lr.
What metal melts at 90 degrees Celsius?
The metal that melts at 90 degrees Celsius is gallium.
How many electrons are there in one atom of Strontium-90?
One atom of Strontium-90 contains 38 electrons.
What are the elements with atomic numbers 58-71 and 90-103 called?
The elements with atomic numbers 58-71 are called lanthanides, and those with atomic numbers 90-103 are called actinides. These elements are part of the inner transition metals and have unique properties due to their electron configurations.
How many electrons does Thorium have?
Thorium, or Th, has an atomic number of 90. That means that every atom of thorium has 90 protons. The only naturally abundant isotope of thorium is 232Th, and so therefore it has 232 - 90 = 142 neutrons.
How many electrons are there in Thorium?
Thorium is a metal element. There are 90 electrons in a single atom.

How much electrons does Thorium have?
90 in ground state
How many electrons does thorium -230 have?
Thorium 230 has 90 protons and 140 neutrons - the difference is 50.
How many electrons does thorium230 have?
Thorium has 90 protons. So for a neutral atom, there has to be 90 electrons. 230 is the total number of nucleons. ie 90 protons and 140 neutrons.
