Can the proportions of magnesium and oxygen in magnesium oxide be changed?
No. Magnesium oxide, MgO, is a compound, which means it is a pure substance, in which the magnesium and oxygen are present in definite proportions, in this case 1:1. This is in accordance to the law of definite proportions, which states that every pure substance always contains the same elements combined in the same proportions by weight. Also, magnesium ions have a charge of 2+ and oxide ions have a charge of 2-, so that one magnesium ion combined with one oxide ion balances to an overall charge of zero.
Which elements have the same number of valence electrons as beryllium?
For example calcium and magnesium.
What element has the same physical and chemical properties as magnesium and strontium?
Calcium has similar physical and chemical properties to magnesium and strontium. They all belong to the same group of the periodic table, which means they have similar reactivity and characteristics.
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
What is the same group of periodic table as magnesium?
Magnesium belongs to group 2 (alkaline earth metals) in the periodic table. Elements in the same group as magnesium include beryllium, calcium, strontium, barium, and radium. They all share similar chemical properties due to having the same number of electrons in their outermost shell.
What does magnesium and beryllium have in common?
Same group
What chemical properties share the same with beryllium?
Magnesium has some similarities with beryllium.
Why do lithium and beryllium form ions with different charges?
Lithium typically forms ions with a charge of +1, while beryllium forms ions with a charge of +2. This difference in charge is due to the number of electrons that each element gains or loses to achieve a stable electron configuration. Lithium needs to lose one electron to achieve a stable configuration, forming Li+ ions, while beryllium needs to lose two electrons to achieve stability, forming Be2+ ions.
Does beryllium or sodium have the same inside electron arrangement as magnesium?
no they have to be in the same group

Does 1 mole of sodium chloride and 1 mole of magnesium chloride has same number of ions?
No: Each "mole", more precisely called "formula mass", of sodium chloride contains two ions, as shown by its formula NaCl, but each formula mass of magnesium chloride has three ions as shown by its formula MgCl2. This is true because sodium cations have only one positive electric charge unit, magnesium cations have two electric charge units, and chloride ions have one negative electric charge unit each.
Which element probably has similar properties to beryllium?
All you have to do is look at which group Beryllium is in and look at the other elements that are in the same column. The gruop of an element can help you determine its chemical properties. That group would be Group 2 with Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
Would beryllium or sodium have properties like to magnesium?
Sodium would have properties more similar to magnesium than beryllium. This is because sodium and magnesium are both in the same group/family (group 2) of the periodic table, known as the alkaline earth metals, whereas beryllium is in group 2. Sodium and magnesium share similar chemical behavior, such as forming similar types of compounds and reactions.
