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.
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.
Helium has only two electrons. It is the first noble gas in the periodic table and has a full outer electron shell.
Yes it does. Helium has 2 electrons in the s orbital. A s orbital can hold a maximum of two electrons.
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
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.
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.
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Magnesium has 2 electrons on its outer energy level.
Helium has only two electrons. It is the first noble gas in the periodic table and has a full outer electron shell.
forgot
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
Yes it does. Helium has 2 electrons in the s orbital. A s orbital can hold a maximum of two electrons.
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
