WebMar 20, 2024 · Gallium is in period 4 on the periodic table and has 31 electrons: ⇒ The first shell is complete with 2 electrons ⇒ The second shell is complete with 8 electrons ⇒ The third shell is complete with 18 electrons ⇒ The fourth shell is left not fully complete, so the remaining 3 electrons are valence electrons in an atom of gallium metal . Answer link WebThe periodic table of the elements contains all of the chemical elements that have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthanoids (lanthanum, 57, to lutetium, 71) and the actinoids (actinium, 89, to lawrencium, 103) indicated separately below. The periods are of varying …
