Almost, but not quite. The halogens are group 17 on the periodic table, and consist of fluorine, chlorine, bromine, and iodine (astatine doesn't really count.) These elements all have 7 electrons in their outer shell, or energy level. To achieve noble gas configuration, they must have 8, so they need one more. Because it's relatively easy to get this one more, they are all quite reactive.

∙ 6y agoThey're quite non-reactive. (the noble gases are elements with filled outer shells)

Chemically inert atoms always have their outermost electron shell full?
True!
Is it true that atoms with fewer that 4 outer electrons lend electrons?
yes
Is an atom is chemically stable if its outer energy level is filled with or contains no electrons?
filled with electrons
Why is the outer shell of electrons thought to be the most important for determining chemical properties?
since the inner shells are filled, it is the outer electrons that take part in the bonding. They can give away 1 or 2 or 3 electrons or take 1 or 2 or 3 to fill their outer ring. Or they can share.electrons in the outer ring.
Does a partially filled outer electron level make an atom stable?
yes that is true, it does make up an atom stable.
When a compound is formed by 2 or more atoms of different elements the outer electron shell of the compound is completely filled with electrons?
This answer is True!
Is it true or false when a compound is formed by two or more atoms of different elements joining the outer electron shell of the compound is completely filled with electrons.?
true
When a compound is formed by two or more atoms of different elements joining the outer electron shell of the compound is completely filled with electrons?
true
For atoms of most elements the outer energy is filled when it has 8 electrons true or false?
true
The chemical and nuclear properties of atoms are largely independent of each other. true or false?
It is true. The chemical properties of atoms are primarily based on the electron configuration, particularly the number of electrons in the outer or valence shell, while the nuclear properties of atoms are primarily based on the proton/neutron configuration in the nucleus.
Does one shell have to be full for there to be electrons in the next shell?
Yes, it is true. Until the inner shell is fully filled-electrons do not enter the next shell.
Chemically inert atoms always have their outermost electron shell full?
True!
What is true of the number of electrons in the outer energy level of nonmetallic atoms?
17.
Is it true that atoms with fewer that 4 outer electrons lend electrons?
yes
Is an atom is chemically stable if its outer energy level is filled with or contains no electrons?
filled with electrons
Is it true that mollusks with a hard outer shell are invertebrates?
Yes, they are invertebrates as they don't have a spine or an internal skeleton.
Are electrons are bounds ti atomic nuclei by strong forces true or false?
Noble gases do have outer energy levels that are completely filled. However, it is not true that these gasses form bonds easily. In fact, because all of the potential "spots" for electrons are already filled, the noble gas is very stable and has no need to bond with other atoms. Because of this, noble gases very rarely chemically bond.
