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.
What else can I help you with?
Chemically inert atoms always have their outermost electron shell full?
This statement is generally true. Chemically inert atoms, such as the noble gases, have a full outer electron shell, which makes them stable and less likely to react with other atoms to form compounds.
True or false if valence electrons are shared between atoms the bond is said to be covalent?
True. In a covalent bond, atoms share valence electrons to achieve a full outer shell and form a stable molecule.
Is an atom is chemically stable if its outer energy level is filled with or contains no electrons?
filled with electrons
Which of the following statements are true about whether atoms tend to gain or lose electrons?
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
True or false atoms of the halogens do not normally form chemical bonds?
False. Atoms of halogens, such as chlorine and fluorine, do form chemical bonds with other elements to achieve a stable electron configuration. Halogens are highly reactive and tend to form bonds with other elements to complete their outer electron shell.
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
Chemically inert atoms always have their outermost electron shell full?
This statement is generally true. Chemically inert atoms, such as the noble gases, have a full outer electron shell, which makes them stable and less likely to react with other atoms to form compounds.
True or false if valence electrons are shared between atoms the bond is said to be covalent?
True. In a covalent bond, atoms share valence electrons to achieve a full outer shell and form a stable molecule.
Is an atom is chemically stable if its outer energy level is filled with or contains no electrons?
filled with electrons
Which of the following statements are true about whether atoms tend to gain or lose electrons?
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
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.
Do atoms combine by sharing electrons?
Atoms share electrons when they form covalent bonds.
Is it true or false that Noble gases are inert gases?
Noble gases are inert gases because of a completely filled valence shell,hence they need not to satisfy their valency.
