Each element has its own number of protons; that is what defines an element. However, generally speaking, the elements in a period have the same number of electrons in their outer shells, with some exceptions of course.
No - elements in groups 1-2 and 13-18 (except helium) have the same number of valence electrons as the other elements in their group. Groups, or families, are vertically arranged while periods are horizontal rows on the table. While trends exist across periods, they do not tend to share similar chemical properties because of their dissimilar numbers of valence electrons.
No. Period 1 only has hydrogen and helium, but its still a period. As well as two and three, they only have 8. But most of the rest (4, 5, 6) have the same amount. Of course seven doesnt have the same amount because there are some squares that have just never been discovered.

No, the first period contains only two elements, H and He, while the second contains 8, and the sixth contains even more with 32 elements in that period.
Please refine the question. The answer to this specific question would be 'no'.
No. It is the columns, not the periods, of the table in which every element (except helium) generally has the same number of valence electrons
Those in vertical groups - so for example
Li, Na, K, Rb, Cs, Fr all have just one
Be, Mg, Ca, Sr, Ba, Ra all have two
F, Cl, Br, I, At all have 7
etc
The number of protons in the atomic nucleus is a value specific for each chemical element.
no it is a group of elements
No, they do not.
All elements in the same group have the same number of valence electrons.
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
There are 8 valence electrons in the noble gases, the family of elements furthest to the right on the periodic table.
Two valence electrons.
All elements in the same group have the same number of valence electrons.
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
Elements with the same number of valence electrons are in the same group (or vertical column).
Just get to know the periodic table of the elements; that is the key to understanding valence electrons.
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
What is the name of the collection of elements on the right side of the periodic table with electrons sequentially filling orbitals in their valence?
They follow a pattern for valence electrons.
yes, the number of dots represent the number of valence electrons in the periodic table.
Elements in every group of the periodic table has some number of valence electrons. The exception is, when it comes to group 18, the number of valence electrons might be considered as either 0 or 8.

There are 8 valence electrons in the noble gases, the family of elements furthest to the right on the periodic table.
