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 :)
How are beryllium and iodine the same?
Beryllium and iodine are different chemical elements.
Why does beryllium and helium have the same valence electrons but not the same chemical properties?
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.
Are halite and hematite minerals that contain the same elements but different numbers of atoms or each element?
No. Halite is sodium chloride. Hematite is iron (III) oxide.
Atoms of different elements are different because they have different numbers of what type of particle?
Atoms are considered to be of the same element if they have the same number of protons. If their atoms have a different number of NEUTRONS, they are known as ISOTOPES of the same element.
Does beryllium or sodium have the same inside electron arrangement as magnesium?
no they have to be in the same group

How are beryllium and iodine the same?
Beryllium and iodine are different chemical elements.
Is there the same number of particles in a mole of sodium a mole of carrots or a mole of elephants?
The number of particles is different The number of sodium atoms, carrots, and elephants are the same 6.02 * 10 ^23 sodium atoms 6.02 * 10 ^23 carrots 6.02 * 10 ^23 elephants
How is a sodium atom different from a sodium atom?
The only possible long-lasting difference between two isolated sodium atoms is that one has more neutrons in its nucleus than the other, so that they are distinct isotopes of sodium. For a short time, atoms of the same isotope of sodium can also be different because one is more excited than the other.
Are the atoms the same or different in hydrogen?
All hydrogen atoms are the same but they are different from the atoms of other elements.
Why do lithium and beryllium form ions with different charges?
Yes they do have the same properties.
What are atoms with the same atomic number but different mass called?
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
Are the atoms of sulphur in the liquid the same as the atoms in solid sulphur?
The atoms in a liquid are the same as the atoms in a solid. They are simply arranged in a different way, and have different energy and different intermolecular forces.
