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.
Electrons are transferred between magnesium and fluorine. Magnesium, which has two electrons in its outer shell, tends to lose these electrons to achieve a stable electron configuration. Fluorine, on the other hand, has seven electrons in its outer shell and readily gains an electron to complete its octet. This transfer results in the formation of ionic bonds, with magnesium becoming a positively charged ion and fluorine becoming a negatively charged ion.
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.
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
