Is there a relationship between the group number of each element and the number of electrons in the outermost energy level?

Yes: group number 1 has 1 valence (outer-shell) electron, group 2 has 2 valence electrons ect, until the noble gases, in group 8, which have 8 valence electrons. This does not include the metals in the middle!
H is the first group 1, Be is the first group 2 B is the first group 3, C is the first group 4, N is the first group 5, O is the first group 6, F is the first group 7 and Ne is the first group 8.
He is the odd one out: because whilst it is in the eighth group, as it has a full outer shell, it only has two electrons. That is because the first shell only requires two electrons to fill it.

∙ 11y agoThe number of outer electrons is the same as the group number.

∙ 14y agoThe group number says how many electrons are in that level. In the tens, just subtract 10 to find out. For example group 16 has 6 valence electrons while group 2 has 2 valence electrons.

What are Valence elcetrons?
Valence electrons are the electrons on the outermost energy shell of an element.
Valence electrons in a sentence?
valence electrons are the electrons found in the outermost energy level of bohr diagram for an element.
How many electrons are in the outermost energy level of most atoms?
This value could vary from element to element and atoms could have 1 to 8 valence electrons.
What element in period 3 has 8 electrons in its outermost energy level?
Argon.
Where are the valence electrons in an atom?
In the outermost shell that has electrons in it, those are called the valence electrons. For example carbon has 6 electrons, but only 4 are valence electrons because there are 2 in the shell in between it and the center of the element and 4 on the outside shell.
What element has its outermost electrons in 7s1?
The element is francium.
What are Valence elcetrons?
Valence electrons are the electrons on the outermost energy shell of an element.
What determines if an element is a specific one?
The electrons in the outermost shell
What are the electrons on an element's farthest or outermost electron shell?
Valence.
What is the relationship between two elements located in the same column on the periodic table?
They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
Valence electrons in a sentence?
valence electrons are the electrons found in the outermost energy level of bohr diagram for an element.
What is the total number of electrons in the outermost energy level?
The velence electron will vary for element to element and can have 1 to 8 valence electrons.
What determines the group an element is placed in?
The number of electrons in the outermost orbital.
The number of electrons in the outermost shell of an element is 5 what is its valency and why?
Its valency is 3 i.e. 8-5.The element is a non metal since it has 5 electrons in the outermost shell.Hence, it is very difficult for the element to loose 5 electrons and would be easier togain 3 electrons .Hence, the element gains 3 electrons and thus we consider its valencyto be 8- no. of valence electrons.
What are the valencyelectrons or valanced electrons and what is their location in an atom?
Valence Electrons are the outermost electrons in an element and they are used for bonding with other elements.
If the outermost electron shell of an element is not filled with electrons to its maxium capacity the element is not chemically active?
false
How many electrons are in the outermost energy level of most atoms?
This value could vary from element to element and atoms could have 1 to 8 valence electrons.
