Its period number is 4 and i have no idea what group it's in im still looking for it...
It's period number is 4.
4
Chromium is a METAL . It is found in the first row /period of the Transition Element.
Since chromium has an atomic number of 24, each atom of it contains 24 protons. The number of neutrons can be found by subtracting the atomic number from the mass number. Thus, chromium-63 has 39 electrons.
Chromium's, or Cr's, atomic number is 24. Therefore each chromium atom has 24 protons. 52Cr is the most stable isotope of chromium and has 52 - 24 = 28 neutrons. The chromium ion, Cr3+, means it has 3 less electrons than neutral chromium, and thus the number of protons and neutrons are unaffected.
If this compound existed it would be called chromium heptoxide. This would imply an impossibly high oxidation number for chromium. Chromium forms a number of oxides including Cr2O3 and a chromium(VI) oxide, chromium oxide peroxide.
