How many moles of Cl ions are needed to completely combine with 0.25 moles of Mg 2 ions?
Since the charge of Mg^2+ ion is 2+ and Cl^- ion has a charge of 1-, each Mg^2+ ion will combine with 2 Cl^- ions to form MgCl2. Therefore, for 0.25 moles of Mg^2+ ions, you will need 0.50 moles of Cl^- ions for complete combination.
What is Mg and Cl?
mg and cl are element abrieviations. most common in chemistry. mg is magnesium and cl is chlorine. you will find them on a periodic table where elements are graphed depending on atomic mass and number, also buy there rate of reaction.
What it the balanced equation for Mg and CO2?
Mg(s) + 3/2 O2(g) + C(s) ----> MgCO3(s)
Why does magnesium chloride have no overall charge?
Magnesium chloride has no overall charge because magnesium, a metal, has a +2 charge, while chloride, a nonmetal, has a -1 charge. When magnesium (Mg) donates two electrons to chlorine (Cl), each forms a stable ion (Mg²⁺ and Cl⁻) resulting in a neutral compound.
What pairs of elements is most likely to form an ionic compound Mg and F or O and Cl?
Mg and F is most likely to form an ionic compound because magnesium (Mg) has a +2 charge and fluorine (F) has a -1 charge, leading to a strong attraction between the two. Oxygen (O) and chlorine (Cl) also form ionic compounds, but the attraction between Mg and F is stronger due to their larger difference in electronegativity.
How much Mg and Cl is in MgCl2?
In one formula unit of MgCl2, there is one atom of magnesium (Mg) and two atoms of chlorine (Cl).
What neutral atoms has the largest atomic size between Li Fl Cl and Mg?
From the given elements, Mg has the largest atomic radius, hence the size.
What has the largest formula mass LiCl NaCl KCl MgCl2.?
MgCl2 has the largest formula mass among the given compounds. This is because the formula mass of a compound is the sum of the atomic masses of all the atoms in a formula unit, and magnesium (Mg) has a greater atomic mass than lithium (Li), sodium (Na), and potassium (K).
Arrange the following ions in increasing order of size Be Cl s na mg br?
From LArgest to smallest it is Br, Mg, Na, Cl, Be.... This is because of ionization the concept is realitivly simple as you go to the right of the peroidic table they do not want to loose there electrons and the attraction of the electrons to the nucleus is greater therefore making the atoms smaller as you go to the right.

What kind of bond is Mg and Cl?
Ionic- the difference in electronegativity is high (Mg 1.31, Cl 3.16)
Arrange the following elements from greatest to least tendency to accept an electron. Cl S Si Mg Na?
From greatest to least tendency to accept an electron, they are F, O, C, Li, and Be.
What are symbols for representative elements Na Mg Fe Ni Cl?
Representative elements belong to s and p block. The elements are Sodium (Na), Magnesium (Mg) and chlorine (Cl)
Is MgCl ionic or molecule?
The high difference in electronegativity between Mg and Cl, and the fact that Mg is a metal and Cl is a non-metal, means that it's an ionic bond. Magnesium has two valence electrons; one chlorine takes one of them, another chlorine takes the other. The formula is therefore MgCl2.
What element is the largest Mg S Na CI?
Sodium (Na) is the largest element among Mg (magnesium), S (sulfur), Na (sodium), and Cl (chlorine) when comparing their atomic radii. Sodium has the largest atomic radius because it is located in the third period of the periodic table, whereas magnesium is smaller due to being in the second period.
Which elements can be joined by a covalent bond K Cl C N Li Cu Fe Xe Mg N?
C and N, N and H, Cl and Cl, Xe and Xe can form covalent bonds. Mg and Cl, Li and Cl, Cu and Cl, Fe and Cl can form ionic bonds due to the large difference in electronegativity. K and Cl would form an ionic bond as well.
