Elements that have the same number of valence electrons are?
All elements in the same group have the same number of valence electrons.
How many elements have electrons at ns2np6?
All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)
Elements in the same period have similar properties?
Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more proton and electron and become less metallic. Hope this helped you with your homework. :P
Define periodicity as it relates to the organization of elements on the periodic table?
The relationship is that the elements are organized by periods. Each row is a period and it goes from left to right. Each row is a period identified by different colors. Elements on the same row have something in common. All of the elements in a period have the same number of atomic orbitals. For example all the elements on the 1st row have only one orbital for its electrons. All the elements on the 2nd period (row) have two orbitals for its electrons. This repeats to period (row) 7. - Brian Tui
Which period 5 element has 5 valence electrons?
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
All of the elements in period 4 are?
all of them are elements with less than 37 electrons.
All of elements in period have same?
Number of Electrons.
The period of elements that are all radioactive?
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
What separates elements into different periods?
The periods on the periodic table separate the elements according to which shell their valence electrons fall into. So, elements located in the third period will have the sum of all electrons contained in that period. For example: P has an electron configuration of 1s2, 2s2, 2p6, 3s2, 3p3 ......................sooo, add up all electrons from the third shell (3s2 & 3p3) to get the total number of valence electrons of the element.
Elements that have the same number of valence electrons are?
All elements in the same group have the same number of valence electrons.
What do periods and groups have in common in a periodic table?
Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that. This also means that the atomic weight of the elements gets larger and larger in each period.
How many elements have electrons at ns2np6?
All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)

What is row on the periodic table called what do they have in common?
The row is called the period. Each element in the same period has the outermost electrons in the same shell (energy level). For example, the elements in the 3rd period all have the outermost electrons in the 3rd shell.
What similaries to element in the same period share?
Elements in the same grope share the same amount of energy shells, and valence electrons.
Which period 5 element has 5 valence electrons?
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
