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

Gaseous elements that have low reactivity found in which group of the periodic table?
Noble Gases
What is the pattern of reactivity observed in the non-metal elements in groups 13-17 of the periodic table?
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
What periodic trends of reactivity occur with the alkali metals?
Reactivity increases the farther down you go in the Periodic Table.
What are some good questions about the periodic table?
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
Are transition metals on the periodic table reactive?
yes, they are less reactive than group 1 and 2. These metals hardly react with air or water at all whereas Group 1 and 2 metals tarnish quickly and react with water
Gaseous elements that have low reactivity found in which group of the periodic table?
Noble Gases
Where are the most reactive nonmetals located on the periodic table?
The most reactive nonmetals are located in top most right section of the Periodic Table, excluding group 18 (has no reactivity).
What is the pattern of reactivity observed in the non-metal elements in groups 13-17 of the periodic table?
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
What periodic trends of reactivity occur with the alkali metals?
Reactivity increases the farther down you go in the Periodic Table.
What is the periodic trend for reactivity of metals?
Metals Period - reactivity decreases as you go from left to right across a period.Group - reactivity increases as you go down a group Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.Non-metals Period - reactivity increases as you go from the left to the right across a period.Group - reactivity decreases as you go down the group. Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron.
What happens as you move down the family on a periodic table the reactivity?
the reactivity of metals increases as you go down a group in the periodic table. also elements in the same group have similar chemical properties because they have the same electronic configuration,i.e.they have the same arrangement of electrons
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
Metal reactivity from left to right in the periodic table.?
Decrease reactivity
In group 1 in the periodic table which element is most active?
In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
How do you tell the reactiveness of a non metal on the periodic table?
The periodicity of nonmetals is that reactivity increases from left to right across a period, through group 17, the halogens. As you move down a group, reactivity decreases. Fluorine is the most reactive element.
What determines the reactive properties of an atom?
the number of elements in the atom The group the element is in on the periodic table (how many valence electrons it has). Metals increase in reactivity from right to left on the periodic table and non metals increase in reactivity from left to right, with the exception of group group 18, which is not reactive, and Hydrogen, which is very reactive.
What are some good questions about the periodic table?
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
