Calcium has atomic number 20. A neutron calcium atom therefore has 20 protons and 20 electrons. Ca2+ has a charge of positive 2, so it must have 2 more protons than electrons. Ca2+ has 18 electrons.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Ununquadium has seven electron shells.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The electron configuration of magnesium is 1s2 2s2 2p6 3s2. Mg+ has one less electron (electrons have negative charge, so a positive charge is a lack of electrons) so you remove one from the outermost orbital: 1s2 2s2 2p6 3s1, or simply [Ne] 3s1.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
The Ca2+ ion is larger than the Mg2+ ion. The ionic radii are: 86pm for the Mg2+ and 114pm for the Ca2+. Besides the fact that the Ca2+ has more electrons this can be explained by the principle of electron shielding. Electron shielding is when lower level electrons block the EFC(effective nuclear charge) from effecting the valence electrons of an ion. Ca2+has more electrons than Mg2+ so more electron shielding occurs.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
Ca2+ is positively charged. Remember that an electron is a particle with negative charge; therefore, the element Calcium (Ca) has LOST 2 electrons in order to be positive 2.

Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
is electronic all have electronic config of {Ar} size Ca^2+^<k+<Cl-<s2-< IE S2-<CL-<K+<CA2+
Calcium loses two electrons; the cation is Ca2+.
Yes, it is identical to Ar.
Calcium must lose 2 electrons and will become Ca2+. It will then have the electron configuration of Argon, a noble gas.
because for it to become an ion it needs to lose 2 electron which means that it would have 2 more proton than electron and proton is positively charged so it becomes 2+
