Two elements with one electron in their outer shells are lithium (Li) and sodium (Na). Both elements belong to the alkali metal group of the Periodic Table.

What is characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens contain seven electrons, and need one more electron to have eight and become stable.
What is characteristic about the outer electron shells of alkali metals?
since all the alkali metals have one electron in there outer most shell so there valency is always one & they are the most electropositive elements in the periodic table.they loose one electron from there outermost shell to form one positive charged cations.
What is the characteristics about the outer electron shells of halogens?
Each halogen element has an outer shell that lacks one electron of being full.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
What are the elements in the first group that have one outer shell electron and that are very reactive called?
The elements in this group are called Alkali Metals.

How many electrons does francium have in its outer most shell?
francium only has one valence electron (one electron in the outermost shell).
What do elements in group 7 have in common?
theyre all diatomic and have the same no. of outer shells
In the first group of elements in the periodic table what does the first group have in common?
They all have one valence electron in their outer shells and so tend to lose that electron in chemical reactions, gaining a +1 charge.
What is a co-valent compound?
a covalent bond involves the elements sharing electrons to fill outer shells rather than one element donating an electron to the other.
How many outer shells does beryllium have?
Beryllium has one outer electron shell with two electrons.
Why are Neon and Argon such nonreactive elements in the periodic table?
Neon (atomic number 10) and Argon (atomic number 18) mostly do not react with other elements because their outermost electron shells have a full complement of electrons. When two elements combine into a molecule they share electrons from their outermost electron shell. This happens when one element has a minimal number of electrons in its outer shell and the other element has an almost full complement of electrons in its outer shell. When they share electrons, they both have the equivalent of full outer electron shells. Since both Neon and Argon have full outermost shells by themselves they do not have a tendency to share electrons.
What is the electronic structure of group 1 elements?
An outer electron shell with only one electron.
What does elements in groop one have in common?
They all have one electron in the outer most shell
How is hydrogen similar from the other elements?
All of them has one electron in their outer shell.
