Both statements are true:
- Every element in group I has one electron in its outer shell
and
- Every element in group II has two electrons in its outer shell

What element has 2 electron shells and 4 valence electrons?
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
What element group gains or shares 1 electrons?
Elements in group 7A can only gain or share 1 electron.
How can i look at the periodic table and tell how many valence electrons an element has?
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
What element has one valence electron but is not a metal?
There is no non-metal with one valence electron. Every element with 1 valence electron belongs to the alkali metals family
How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
What element has 2 electron shells and 4 valence electrons?
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
How many electrons does group 1 have in there outer shell?
There are only one electron. They are called alkaline metals.
How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
What element group gains or shares 1 electrons?
Elements in group 7A can only gain or share 1 electron.
How can i look at the periodic table and tell how many valence electrons an element has?
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
What element has one valence electron but is not a metal?
There is no non-metal with one valence electron. Every element with 1 valence electron belongs to the alkali metals family
Which element group have the most positive electron affinities?
The group that has a substantial affinity for electrons is group 17, the halogens. These elements have 7 valence electrons which makes them have the highest affinity for electrons.
How many electron shells and how many valence electrons are in an atom of an element found in period 3 and group 16 of the periodic table?
This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
How many valence electron are in a baruim?
Barium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, barium has 2 valence electrons.
What can be said about the electron configurations of all the elements in a group?
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
How does an element in group 2 attain a stable electron configuration?
It loses 2 electrons and becomes a +2 ion.
