What else can I help you with?
Atoms of elements in the same group or column have the same number of what?
shells
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
What do elements have across a series have the same number of?
Assuming that series is used the same way as group in the periodic table, elements in the same series have the same number of valence electrons.
What does it mean when two or more elements are in the same row on the periodic table?
It means that the elements have same number of shells. Period determines the number of shells of an element.
Why do elements as a family or group share similar properties?
Elements in the same group have the same number of valence electrons, which determines their chemical properties. This leads to similarities in reactivity and chemical behavior among elements in the same group.
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.
How are the electron clouds of the atoms of the elements in a group the same?
Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
Do elements in the same group or period have similar properties?
Elements in the same group have similar properties because they have the same number of valence electrons. In contrast, elements in the same period do not necessarily have similar properties, as their chemical behavior is determined by the number of electron shells they have.
Elements that are found in the same group have the same number of?
They have the same number of electrons on their outer shells Hope this helped, if it does please recommend me it would be much appreciated

What are the groups on the periodic table and how do they relate to the periodic period of elements?
The groups on the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. The periodic period of elements refers to the horizontal rows on the periodic table, which indicate the number of electron shells an element has. Elements in the same period have the same number of electron shells, but elements in the same group can be in different periods.
What characteristics is shared by elements in the same period?
Elements in the same period share the same number of electron shells, or energy levels. This means they have similar atomic sizes and exhibit similar chemical properties due to their outermost electron configuration.
What do elements have across a series have the same number of?
Assuming that series is used the same way as group in the periodic table, elements in the same series have the same number of valence electrons.
What do elements in each group or family have in common?
Elements in the same group or family have similar chemical properties because they have the same number of electrons in their outermost energy level. This leads to similar reactivity and bonding behavior. Additionally, elements in the same group often have similar physical properties, such as melting and boiling points.
What does it mean when two or more elements are in the same row on the periodic table?
It means that the elements have same number of shells. Period determines the number of shells of an element.
What is the same for all elements in a column?
they have the same number of valence electrons
