WebDec 15, 2012 · Calcium normally has 20 electrons. Because it has a plus 2 charge, it must have two less electrons. Therefore, the calcium ion has 18 electrons. What element has 20 protons... WebFor instance, the ground state electronic configuration of calcium (Z=20) is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. The calcium ion (Ca 2+ ), however, has two electrons less. Hence, the electron configuration for Ca 2+ is 1s 2 2s 2 2p 6 3s 2 3p 6. Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4).
WebNov 11, 2012 · The calcium ion has 18 electrons. The sulfate ion has 16 electrons from sulfur, 32 electrons from oxygen atoms and two from the charge. Altogether, a (molecule) … WebAug 13, 2024 · The electrons always fill the lowest energy levels available until that level is filled, then electrons fill the next energy level until it is filled. This continues for all of the electrons in an atom. We can show the electron arrangement as (2, 8, 2) representing the electrons in the n = 1, n = 2, and n = 3 levels, respectively. Figure 2.4. 2 ...
WebThis means that calcium s2 has 2 valence electrons it readily gives away in order to seek the stability of the octet. This makes calcium a Ca+2 cation. Chlorine is a Halogen in the 17th column or s2p5 group. Chlorine has 7 valence electrons. It needs one electron to make it stable at 8 electrons in its valence shells. WebFeb 8, 2016 · See answer (1) Copy. Calcium has 20 electrons and oxygen has 8 electrons, so the TOTAL number of electrons in CaO is 28. If you mean how many valence electrons are used, then calcium uses 2 ...
WebJul 4, 2024 · Why does chloride have 18 electrons? Since calcium lost two electrons, it has 20 protons, but only 18 electrons. Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons. This makes each chloride a negative ion with a charge of −1. Oppositely charged ions attract each other, forming an ionic bond.
