The nucleus of a sodium atom contains 11 protons and the nucleus of a magnesium atom contains 12 protons. The number of neutrons vary with the isotope. The number of protons determines the identity of an element.

∙ 12y agoIt is very hard to 'predict' density from (or 'relate' it to) other common physical or chemical properties. For the same reason it is not easy to explain the differences.
- Compare diameters: Na = 370 pm, Mg = 320 pm
- Compare Atomic Mass : Na = 23 , Mg = 24.3
- Compare densities: Na = 0.97 g/L, Mg = 1.74 g/L

Why is an iron atom a different element than a sodium atom?
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
Why is it easier to remove an electron from a sodium atom than from a magnesium atom?
Phosphorus has a higher energy level so it pulls harder on its electrons.
What isotope has 11 protons12 neutrons and 11 electrons?
The number of protons in an atom determines what that atom is called. Therefore, sodium, or Na, always has 11 protons. The particular isotope of sodium that has 12 neutrons is called 23Na, and is the only stable isotope of sodium.
How are sodium and chlorine ions different from salt molecules?
A sodium ion is a sodium atom missing one electron. A chlorine ion is a chlorine atom with an extra electron. A salt molecule is a sodium ion stuck to a chlorine ion.
What is the difference between sodium ion and neon atom?
They all have full outer shells. in other words 8 electrons in the outer shell
How is an atom of the element sodium structurally different from an atom of magnesium?
A sodium atom has 11 protons and 11 electrons including 1 outer shell electron A magnesium atom has 12 protons and 12 electons of which 2 are in the outer shell. Sodium loses its valence electron more easily than magnesium does, making the sodium much more reactive.
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
a larger nuclear charge
Oxygen fluorine sodium magnesium aluminium and neon which one is a single atom?
neon
When atom of sodium combines with an atom of fluorine what the new name?
It makes a sodium fluoride or NaF molecule.
How is carbon atom different from a sodium atom?
hi, a carbon atom has 6 protons while sodium atom has 7 protons.
What does one sodium atom plus one chloride atom makes up?
One formula mass of the salt sodium chloride.
Why is an iron atom a different element than a sodium atom?
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
Why sodium and magnesium form positive ions?
Sodium and magnesium form positive ions because they lose electrons in order to have a filled valence shell, like a noble gas. A sodium atom loses one electron so that its ion has a 1+ charge and the noble gas configuration of neon. A magnesium atom loses two electrons so that its ion has a charge of 2+ and the noble gas configuration of neon.
Why does magnesium metal melt at higher temperature than sodium metal?
Due to one unit more nuclear charge and two binding electrons for Magnesium atom.
How many nuetrons are in an atom of magnesium?
there are 12 nuetrons in an atom of magnesium
Is magnesium an ion or an atom?
Magnesium is an atom; but this atom can be transformed in an electrically charged atom - called cation, Mg2+.
Why is it easier to remove an electron from a sodium atom than from a magnesium atom?
Phosphorus has a higher energy level so it pulls harder on its electrons.
