What type of bond do magnesium and sulfur form?

Explanation:

Number

Since 1s can only hold two electrons the next 2 electrons for magnesium go in the 2s orbital. The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s 2 2s 2 2p 6 3s 2. Magnesium: Element Name: 24.31: Average Atomic Mass: The atomic weight is basically a measurement of the total number of particles in an atom 's nucleus including both protons and neutrons. So the first step is to locate the atomic mass on the periodic table, and round the value to the nearest whole number. Therefore, the number of electrons in neutral atom of Magnesium is 12. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.

Magnesium, #'Mg'#, is located in period 3, group 2 of the periodic table, and has two electrons on its outermost shell, i.e. twovalence electrons**.

On the other hand, sulfur, #'S'#, is located in period 3, group 16 of the periodic table, and has six electrons on its outermost shell.

As you know, chemical reactivity is governed by an atom's 'desire' to have a stable electron configuration, that is, to have eight electrons in its outermost shell #-># a complete octet.

In this case, magnesium can complete its octet by giving up those two valence electrons, becoming the magnesium cation. #'Mg'^(2+)#, in the process.

Sulfur, which only needs two electrons to complete it octet, will pick up the two electrons coming from magnesium, becoming the sulfide anion, #'S'^(2-)#, in the process.

The electrostatic force of attraction will then bring the magnesium cations and the sulfur anions together #-># an ionic bond Download adobe indesign for mac. is formed.

What are the quantum numbers of Mg?

1 Answer

Explanation:

When asked the quantum numbers of an element, the question is really asking about only the valence or outermost electron.

Number Of Electrons In Magnesium

The four quantum numbers determine the state of the electron, and are

#n# is the distance of the orbital from the nucleus (#1, 2, 3, 4# etc),
#l# is the shape of the orbital (#0 -> n-1#)
#m_l# is the orientation of the orbital in space (#-l -> +l#), and
#m_s# is the spin of the electrons inside the orbital (#-1/2# or #+1/2#).

The electronic configuration for magnesium is #1s^2 2s^2 2p^6 3s^2#. The outermost electron is one in the #3s# orbital, which means that #n = 3#.

It also means that #l = 0#, since #s# is basically shorthand for the orbital shape of #l = 0#.

#m_l# can range from #-l# to #+l#, but since #l = 0#, then #m_l# must also be #0#.

Finally, #m_s# can be either one since there are two electrons in the #3s# orbital and it doesn't really matter which spin you choose.

Putting all of these together, the final quantum numbers of a magnesium atom are

#3, 0, 0, +-1/2#
