Yes, Mg is more electronegative than Ca. By the Pauling scale Mg has an electronegativity value of 1.31 while Ca has 1.00. The higher the value, the more electronegative the element is. The electronegativity of the elements generally decrease down group II (the alkaline earth metals).
Yes, calcium oxide has a higher lattice energy than magnesium oxide. This is due to the higher charge of the calcium ion compared to the magnesium ion, leading to stronger electrostatic attraction between the ions in the lattice structure.
Fluorine is more electronegative than calcium. Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond, and fluorine has a higher electronegativity value than calcium.
Zinc has more electrons in its outer energy level than Calcium. Because of this, itsnucleus is more attracted to this energy level and pulls it more the nucleus in Calcium. Because of this greater attraction it is harder to remove the electron from Zinc.
Magnesium is more reactive than copper because if you study the periodic table, you will be able to find out that Magnesium is more reactive.Also, coins are made out of copper, they choose copper because it is cheap and extremely unreactive.Furthermore, I've done an experiment to find out that Magnesium is more reactive than Copper by putting both elements into Water/Acid.
EDTA forms more stable complexes with calcium than with magnesium. This is due to the higher charge density and smaller size of the calcium ion, which allows it to form stronger bonds with the EDTA molecule.
The electronegativity of caesium is higher.
No, oxygen is more electronegative than calcium. Oxygen has a higher electronegativity value on the Pauling scale compared to calcium, indicating it has a stronger tendency to attract electrons in a chemical bond.
Yes, calcium can displace magnesium in certain chemical reactions. This is more likely to happen when calcium is in a higher oxidation state than magnesium, allowing it to take the place of magnesium in a compound or reaction.
No, fluorine is more electronegative than calcium. Fluorine has a higher electronegativity value (3.98) compared to calcium (1.00) on the Pauling scale, indicating that fluorine has a greater ability to attract electrons in a chemical bond.
Yes, calcium oxide has a higher lattice energy than magnesium oxide. This is due to the higher charge of the calcium ion compared to the magnesium ion, leading to stronger electrostatic attraction between the ions in the lattice structure.
Cesium has the lowest electronegativity among the elements listed. Helium has the lowest electronegativity overall as it is a noble gas and does not typically form bonds. Calcium has higher electronegativity than cesium but lower than fluorine, which has the highest electronegativity among the listed elements.
Fluorine is more electronegative than calcium. Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond, and fluorine has a higher electronegativity value than calcium.
Uranium is not more reactive than magnesium. Magnesium is more reactive than uranium. Magnesium reacts with water to form magnesium hydroxide and hydrogen gas, while uranium is relatively stable and does not react as readily with water.
Gallium. Ga electronegativity 1.81; Calcium 1.00.
Calcium carbonate is generally a stronger acid than magnesium carbonate. This is because calcium is positioned higher in Group 2 of the periodic table than magnesium, meaning calcium has a greater tendency to lose its outer electrons and behave as an acid.
A mixed calcium and magnesium supplement (such as dolomite) is better than taking just calcium or just magnesium.
Oxygen: It has higher electronegativity than any of the others listed.
