Hydrogen is grouped with alkali metals because it?
it has one electron in its outer energy level like all alkali metals
What group is an element with an outer level electron configuration consisting of one electron in the d orbital and two electrons in the ns orbital?
The elements in group 16 on the periodic table have four total electrons in their outer p orbitals.
How many electrons are in the outer energy level of group 7 a elements?
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
Why is hydrogen placed in group one of the periodic table?
Group one metals are the Alkali Metals, but Hydrogen is placed in group one because of its electron arrangement. All group one metals have one electron in their valence shell (outer most shell) and hydrogen is no exception. It has one electron in its last shell, and is therefore placed in group one even though it is not an alkali metal.
What is the group that has one electron in its outer level?
alkali metal
The group that needs one more electron to fill its outer energy level?
Halogens
Which group metals are very reactive with one electron in the outer energy level?
Alkali metals
Hydrogen is grouped with alkali metals because it?

What group is an element with an outer level electron configuration consisting of one electron in the d orbital and two electrons in the ns orbital?
The elements in group 16 on the periodic table have four total electrons in their outer p orbitals.
What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
How many electrons are in the outer energy level of group 7 a elements?
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
How many electrons are in the outer energy level of the atoms of alkali earth metals?
There are two electrons on the outer shell which means they are pretty reactive. (make bonding easier)
What is the name of the group with only one electron in their outermost energy level?
name the group of elements that have only one electron in their outermost energy level
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
What is the electronic structure of group 1 elements?
An outer electron shell with only one electron.
How many outer levels does Cesium have?
One electron in outermost energy level.
