Which has the largest mass A 3 mol of magnesium B 1 mol of sucrose c12h22o11 C 10 mol of helium?
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.
What else can I help you with?
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?
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
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?
Where are the sources for element helium?
Helium is primarily sourced through natural gas deposits, where it is a byproduct of the gas extraction process. It can also be extracted from the atmosphere, but this method is less common due to the low concentration of helium in the air. The largest helium reserve in the world is the National Helium Reserve located near Amarillo, Texas.
How do you write the formula for helium and magnesium?
The chemical symbol of helium is He; the chemical symbol of magnesium is Mg.
What element would be the most different from magnesium?
The element that would be most different from magnesium is helium. Helium is a noble gas located in Group 18 of the periodic table, while magnesium is an alkaline earth metal in Group 2. Helium is a gas at room temperature and does not typically form compounds, whereas magnesium is a solid and readily forms compounds.
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 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.
Which element have two valence electrons?
Calcium (Ca) has two valence electrons.
Does helium has the same amount of electrons in its outer shell as magnesium?
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
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.

Why helium and magnesium are both elements and not compound?
Helium and magnesium are both elements because they consist of only one type of atom. In contrast, compounds are made up of two or more different elements chemically bonded together. Helium and magnesium exist in their pure forms as single atoms without being chemically combined with other elements.
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.
