What are elements of a group that has the same number of shells?
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
What part on periodic table shows number of shells of nucleus of atom?
The period number is equal to the number of shells. Periods are the horizontal rows on the periodic table. The number of shells increases down a group.
What does the group of the periodic have to do with reactivity?
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
Atoms of elements in the same group or column have the same number of what?
shells
Which element is in group v of the periodic table and has 3 electron shells?
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
What are elements of a group that has the same number of shells?
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
What part on periodic table shows number of shells of nucleus of atom?
The period number is equal to the number of shells. Periods are the horizontal rows on the periodic table. The number of shells increases down a group.
What do you notice about the number of enery level or shells as you move down a group or column in the periodic table?
As you move down a group or column in the periodic table, the number of energy levels or shells increases. Each row in the periodic table represents a different energy level, with elements in the same row having the same number of electron shells.

Atoms of elements in the same group or column have the same number of what?
shells
What is the group of 17 elements is called?
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
Which way does electron shells increase on the periodic table?
The number of shells in periodic table increase down the group, i.e., vertically.
Which element is in group v of the periodic table and has 3 electron shells?
The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
What is the number of the family group with atoms that all ready have full valence shells?
The family is Group-18. They are noble elements.
What is the difference between a period and a group in the periodic table?
Groups run vertically downwards and periods run horizontally from left to right. The group number of an element usually tells the number of valence electrons (free electrons) in its atom and the period number tells the number of shells an atom possesses e.g. elements of group 3 will have 3 shells in total. Hope this helps :)
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
What similaries to element in the same period share?
Elements in the same grope share the same amount of energy shells, and valence electrons.
