Since magnesium and helium do not form elemental molecules, a mole of these elements is the same as a gram Atomic Mass, which is 24.305 for magnesium and 4.00260 for helium. The gram molecular mass for sucrose is 342.30.
Therefore, the mass of:
A. 3 moles of magnesium is 72.915 grams;
B 1 mole of sucrose (C12H22O11) is 342.30 grams; and
C. 10 moles of helium is 40.0260 grams.
The largest of these is obviously the single mole of sucrose.

Does magnesium have a smaller radius than helium?
Atoms do not have a radius. A helium atom has a nucleus composed of at least two protons and maybe one or two neutrons. A magnesium atom nucleus (and every other atom on the periodic table other than hydrogen) is BIGGER than a helium nucleus. So if you look at it that way...magnesium is larger than helium
Does helium has the same amount of electrons in its outer shell as magnesium?
yes
What element out of lithium neon silicon helium and chlorine have a filled outermost shell?
Magnesium
Is helium more reactive that magnesium?
No, helium is a noble gas, meaning it has a full outer electron shell. It does not need to gain or lose electrons to become stable, so it is almost completely inert. Hydrogen on the other hand, is extremely reactive as it only needs one electron to become stable. This is why the Hindenburg airship exploded, and why we use helium in similar craft today.
Which atom has the largest electronegativity value?
which atom in a water molecule has the greatest electronegativity?
How do you write the formula for helium and magnesium?
The chemical symbol of helium is He; the chemical symbol of magnesium is Mg.
Which element have two valence electrons?
Magnesium
What element would be the most different from magnesium?
Na would be the most different from Magnesium.

Does helium atom has the same number of electrons in its outer shell as in magnesium atom?
yes, both helium and magnesium have 2 valence electrons. the difference is that in helium, the 2 electrons make up an entire electron level. In Magnesium, they only make up the s orbital, or 1st electron sub-level.
Does helium has the same amount of electrons in its outer shell as magnesium?
yes
What is the largest noble gas?
Radon is largest. Helium is smallest
Do helium has the same number of electrons in the outer shell as in magnesium?
Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.
What element out of lithium neon silicon helium and chlorine have a filled outermost shell?
