What element has the same physical and chemical properties as magnesium and strontium?
beryllium
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.
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
There are the same number of atoms in one mole of beryllium as there are in one mole of magnesium :)
Which elements have the same number of valence electrons as beryllium?
For example calcium and magnesium.
What are two elements that are in the same family as magnesium?
Magnesium is an alkali earth metal. Beryllium and calcium are also alkali earth metals.
What does magnesium and beryllium have in common?
Same group
What chemical properties share the same with beryllium?
Magnesium has some similarities with beryllium.

Does beryllium or sodium have the same inside electron arrangement as magnesium?
no they have to be in the same group

Why do lithium and beryllium form ions with different charges?
Yes they do have the same properties.
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.
What are two elements that are in the same family as magnesium?
Magnesium is an alkali earth metal. Beryllium and calcium are also alkali earth metals.
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.
What is the same group of periodic table as magnesium?
Magnesium is present in group 2 of periodic table which also contains Beryllium, Calcium, Strontium, Barium and Radiium.
