In terms of electrons in the periodic table why are group 1 metals very reactive and group 7 non-metals very reactive too?

Atomic elements typically want to have full electron shells ("valence shells"), instead of shells with uneven numbers.
Group 1 metals have only 1 electron in their valence shell, so they quickly react to lose this electron and have an empty shell (but a full shell underneath it).
Group 7 elements have 7 valence electrons and react quickly to steal another atom's electron and gain a full shell of 8 electrons.
This willingness to lose or steal electrons makes the elements very reactive, but in different ways. Group 1 elements will become positively charged ions, and Group 7 will become negatively charged. (Na+ versus Cl-)
Group 6 elements (such as oxygen) are also somewhat reactive and will steal 2 electrons to become even more negatively charged (O 2-)

∙ 10y agoIt is not the groups that are reactive but the atoms. Atoms react because they contain an unstable number of electrons and by reacting can reach a more stable number of electrons.

What are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Where are less reactive metals nonmetals and metalloids on the periodic table?
in groups 1 and 2 :D
The most reactive metal among the following is?
The most reactive metals of the periodic table are those that belong to alkali group. Among this group, the more electrons contain each atom of each element, the more reactive it is. This is why Francium is the most reactive of alkali metals.
When nonmetals and metals react which atom electrons?
Metals loss electrons and nonmetals gain electrons.
What is the most reactive family of nonmetals and metals?
The most reactive nonmetals are in group 17 (halogens). The most reactive metals are in group 1 (alkali metals).
Is unreactivity a property of metal?
No, because metals are on the left side of the Periodic Table. Therefore, they are reactive. Nonmetals, on the left side of the Periodic Table, are less reactive, because they have more valence electrons.
What groups are the very reactive elements from?
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
In which family in the periodic table are the most reactive nonmetalsmily in the periodic table are the most reactive nonmetals?
halogenes/non metals
What are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Which reactive element will gain or loses an electron?
Generally metals lose electrons and nonmetals gain electrons.
What term describes the reactive nonmetals that have seven valence electrons?
alkali earth metals
Where are less reactive metals nonmetals and metalloids on the periodic table?
in groups 1 and 2 :D
The most reactive metal among the following is?
The most reactive metals of the periodic table are those that belong to alkali group. Among this group, the more electrons contain each atom of each element, the more reactive it is. This is why Francium is the most reactive of alkali metals.
What is the most reactive group of a metals and nonmetals?
Metals: alkaline metals Nonmetals: halogens
When nonmetals and metals react which atom electrons?
Metals loss electrons and nonmetals gain electrons.
What are the three major groups of elements on the periodic table?
The three classes of periodic elements are:Metals,that usually tend to lose electrons to form positive ions.Semi-metals or MetalloidsNon-metals,that usually tend to accept electrons to become negative ions.
What is the most reactive family of nonmetals and metals?
The most reactive nonmetals are in group 17 (halogens). The most reactive metals are in group 1 (alkali metals).
