There are 6 valence electrons in tellurium On the 5th energy level, it's valence shell
6
They are the electrons in the outermost shell, and are the ones involved in most chemical reactions.
Eight valence electrons would complete the out shell. If the outer shell was complete it would still be called the same thing, however the charges would be different.
The valence electrons of manganese are located in the 4s and 3d energy levels.
To answer this, we simply need to consider the lightest of the chemical elements, hydrogen. Hydrogen's atomic number, and thus its number of protons and electrons, is 1. So, by necessity, that is the minimum amount of valence electrons an atom can have.
This would be Sb - Antimony.
The element tellurium would be expected to form 2covalent bonds in order to obey the octet rule.Te is a nonmetal in group 6A, and therefore has 6 valence electrons. In order to obey the octet rule, it needs to gain 2 electrons. It can do this by forming 2single covalent bonds.
An atom of chlorine has 7 valence electrons because it is in group 17 of the periodic table.
6
The are none.

An inner electron, such as those found in the core of an atom, would be a non-example of a valence electron. These electrons are not involved in chemical bonding and are therefore not considered valence electrons.
They are the electrons in the outermost shell, and are the ones involved in most chemical reactions.
The atoms with six valence electrons are the elements of group sixteen. This list includes O, S, Te, Se, and Po. If you would like to answer this yourself, just remember that the last digit of the group number is typically the number of valence electrons that you will have. The exceptions of course are the transitional metals from group 3 to 12 and the lanthanides and actinides like uranium and plutonium. These have 2 valence electrons.
Helium has 2 valence electrons, and it's the only noble gas that doesn't have 8 valence electrons.
