Magnesium and calcium will each donate up to two electrons (and prefer to donate both) to an ionic bond with some more electronegative atom / ion.
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
Magnesium often bonds ionically. It has 2 spare electrons in the outer shell (a charge of 2+) , so therefore has a valency of 2.magnesium can also bond covalently forming 2 bonds as in the Grignard reagent, ethyl magnesium bromide, C2H5MgBr. This is an organometallic compound.
A typical magnesium atom has 2 electrons in its outer shell. Magnesium is in Group 2 of the periodic table, so it has 2 electrons in its outermost shell.
Magnesium chloride is an ionic compound. Magnesium has 2 valence electrons, and chlorine has 7. According to the octet rule, each element will bond in such a way that it ends up having 8 electrons in its outer shell--either by adding electrons to its outer shell until it has 8, or by losing all the electrons in its outer shell (that way, the next-largest electron shell--which is already full--becomes the new outer shell). Since magnesium has 2 valence electrons, it will lose two electrons (it's easier to go 2 - 2 = 0 than to go 2 + 6 = 8). Chlorine has 7, so it will gain an electron and have a full (8-electron) outer shell. There must therefore be two chlorines for every magnesium: each chlorine accepts one of the two electrons donated by magnesium. Magnesium forms two ionic bonds: one to each chloride ion.
Magnesium has two electrons in its outermost shell.
Magnesium has 3 outer electron shells. It has 12 electrons with 2 in the first shell, 8 in the second shell, and 2 in the third shell.
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
Magnesium needs to lose 2 electrons to achieve a full outer shell configuration, as it has 2 electrons in its outer shell. By losing these 2 electrons, magnesium becomes a positively charged ion with a full outer shell.
2 Because Magnesium only has 2 electrons in it's outer shell
False - calcium forms ionic bonds very easily because it has only 2 electrons in its outer shell
