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.

Three. Two chlorine atoms and one magnesium atom.


How many moles are contained in 444 grams of magnesium chloride?

To find the number of moles in 444 grams of magnesium chloride, you first need to calculate the molar mass of magnesium chloride. The molar mass of MgCl2 is about 95.21 g/mol. Next, calculate the number of moles by dividing the given mass by the molar mass: 444 g / 95.21 g/mol ≈ 4.66 moles of magnesium chloride.


What are the common compounds of magnesium?

Common compounds of magnesium include magnesium oxide (MgO), magnesium chloride (MgCl2), magnesium sulfate (MgSO4), and magnesium hydroxide (Mg(OH)2). These compounds are used in various applications ranging from healthcare to industrial processes due to magnesium's diverse properties.

What is the importance of Magnesium Chloride in PCR?

An essential cofactor for the DNA polymerase in PCR is Magnesium chloride. Its concentration must be optimized for every primer:template system. Many components of the reaction bind magnesium ion, including primers, template, PCR products and dNTPs. The main 1:1 binding agent for magnesium ion is the high concentration of dNTPs in the reaction. Because it is necessary for free magnesium ion to serve as an enzyme cofactor in PCR, the total magnesium ion concentration must exceed the total dNTP concentration. Typically, to start the optimization process, 1.5 mM magnesium chloride is added to PCR in the presence of 0.8 mM total dNTPs. This leaves about 0.7 mM free magnesium for the DNA polymerase. In general, magnesium ion should be varied in a concentration series from 1.5-4.0 mM in 0.5 mM steps.I just read somewhere that some PCR reagents require free Mg2+

How many elements are joined together to form magnesium chloride?

Magnesium chloride is composed of one magnesium atom and two chlorine atoms, making a total of three elements that are joined together to form magnesium chloride.


Is magnesium and chlorine a likely compound?

It's an actual, and common, compound - MgCl2 (magnesium chloride), a constituent of seawater, has many uses including just chasing off the chlorine atoms to recover the magnesium metal.


How many chloride ions are needed to cancel the 2 charge of magnesium in magnesium chloride (MgC12)?

Two.


How many chloride ions are present in a formula unit of magnesium chloride?

In a formula unit of magnesium chloride (MgCl2), there are 2 chloride ions present. This is because magnesium has a +2 charge and chloride has a -1 charge, so it takes two chloride ions to balance the charge of one magnesium ion.


How many chloride atoms will magnesium bond?

Magnesium atoms, which form divalent cations, can each bond ionically with two chloride ions, because chlorine atoms form anions with only one negative charge each. ("Chloride atoms" as written in the question do not exist: chlorine atoms form chloride ions by gaining one electron each from less electronegative atoms.)


How many soluble chlorides are there?

Which solution will react with magnesium metal?

Magnesium is very reactive and will react with many different solutions including those composed of acids. Example: 2HCl(aq)+Mg(s)->H2(g)+MgCl2(aq)


What does the formula for the compound magnesium chloride MgCl2 tell you about how many chloride ions are needed to cancel out the charge of magnesium?

The formula MgCl2 indicates that one magnesium ion (Mg2+) requires two chloride ions (2Cl-) to cancel out its charge. Each chloride ion carries a charge of -1, so two chloride ions are needed to balance the +2 charge of magnesium.


What is the gas given of when magnesium reacts with acid?

there are many many acidic corosive materials. you will need to be more specific as in what type of acid the magnesium is reacting with. i assume you are at school and are talking about hydrochloric acid. If you add Magnesium metal to hydrochloric acid , the Magnesium will dissolve and form bubbles of hydrogen gas.


How many chloride ions are present in a formula unit of magnesium chloride given the charge of a mg ion is 2 plus?

There are two chloride ions present in a formula unit of magnesium chloride. This is because the magnesium ion has a 2+ charge, requiring two 1- chloride ions to balance the charge in a 1:2 ratio.


How many chloride ions are present in a formula unit of magnesium chloride given the charge on a mg ion is 2 plus?

Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.
