Since Te 2- has a negative charge, there are more electrons. Two more in fact. This means Te (with a atomic number of 52, equaling the number of electrons) with two more electrons would be a total of 54 electrons.
Te 2- has 54 electrons.
Tellurium (Te) has six valence electrons.
Helium-4 has 2 electrons.
Magnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
4 electrons, 2 valence electrons
There are 2 electrons in an oxygen ion with a charge of -2. This is because oxygen normally has 6 electrons, but when it gains 2 extra electrons to become an ion with a charge of -2, it now has 8 electrons total.
Tellurium (Te) has an atomic number of 52, meaning it typically has 52 electrons when neutral. When it forms an ion, the number of electrons changes based on its charge. For example, if Te forms a -2 ion (Te²⁻), it would have 54 electrons, while if it forms a +4 ion (Te⁴⁺), it would have 48 electrons.
Tellurium (Te) has six valence electrons.
The valence of tellurium (Te) is typically -2, meaning it tends to form compounds where it has gained 2 electrons.
Te-128 has 52 protons, 52 electrons, and 76 neutrons.
It could be telluride, which is tellurium (Te, #52) when it gains 2 electrons. Its ionic symbol would be Te-2.
Helium-4 has 2 electrons.
1s electrons = 2 2s electrons = 2 3s electrons = 2 4s electrons = 2 so a total of 8
