The elements of this group do not have a stable number of electrons.
- - - - -
Group 17, the halogens, are extremely reactive (the only non-reactive elements are in group 18, the noble gases, but group 17 elements are more reactive than other group elements) because of their high "effective nuclear charge." An atom wants to have eight electrons in its outer shell, whether it's because it naturally has that many like the group 18 elements do or because it bonded to other atoms and share electrons with them. The closer to eight an atom has on its own, the higher this charge is - which makes it more reactive. Group 17 atoms all have seven electrons in their outer shells, so they are on the hunt for anything they can possibly grab.
For more entertainment, the fewer shells an atom has between its "helium layer" (that lil' shell right around the nucleus with two electrons in it) and the outer shell, the higher this effective nuclear charge is. Because fluorine only has two shells, its effective nuclear charge is as high as it can get...which is why fluorine will react with anything including glass.
Group 1 elements have one valence electron. If they lose one electron, they will attain noble gas configuration and obey octet rule. Hence group 1 elements are reactive and tend to lose one electron.
Group 17 elements have seven valence electron. If they gain one electron, they will attain noble gas configuration and obey octet rule. Hence group 17 elements are reactive and tend to gain one electron.
Because they have to lose and gain only one electron which is easier.

Is selenium reactive?
yes, it is a non metal and it is placed on the right side of the Periodic Table, reactivity increases from left to right on the periodic table. since selenium is in group 16 out of 18 groups, it is a very reactive element. hope this helps you!
If a group of 8 is an octet what is a group of 16 called?
A group of 16 is called a sextet.
What are the reactive elements on the periodic table?
The reactive elements on the periodic table are typically found in groups 1 and 2 (for example, alkali metals like sodium and potassium) and groups 16 and 17 (for example, halogens like chlorine and fluorine). These elements are reactive because they readily form compounds with other elements to achieve a stable electron configuration.
Is 16 pints more than 2 gallons?
Yes, 16 pints is more than 2 gallons. There are 8 pints in a gallon, so 2 gallons is equal to 16 pints.
Which group contains whose atoms have six electrons in their outer level?
Group 16 (group 6A)
What is the nonmetal in period 4 that is more reactive than selenium?
The nonmetal in period 4 that is more reactive than selenium is sulfur. Sulfur is located above selenium in the same group (group 16) on the periodic table, making it more reactive due to its higher electronegativity and tendency to gain electrons in chemical reactions.
Which is more reactive sodium or sulfur?
Sodium is more reactive than sulfur because sodium belongs to Group 1 of the periodic table, which means it has one valence electron that it readily gives up to form compounds. Sulfur, on the other hand, belongs to Group 16 and tends to gain electrons to form compounds, making it less reactive than sodium.
Is chlorine more reactive than sulfur?
Yes, chlorine is more reactive than sulfur. Chlorine is in Group 17 of the periodic table, making it a halogen with a high reactivity towards other elements. Sulfur is in Group 16 and is generally less reactive than chlorine.
What family is beryllium most reactive with?
Beryllium react with the members of halogens family (group 17) and chalcogens (group 16).
Which group are highly reactive non metals on the periodic table?
The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
What element in group 16 has more protons than sodium but fewer than Aragon?
Sulfur (S)
What element in group 16 has more protons than sodium but fewer protons than argon?
The element in group 16 with more protons than sodium but fewer protons than argon is sulfur (S). Sodium has 11 protons, sulfur has 16 protons, and argon has 18 protons.
What is 16 more than -31?
16 more than -31 = -15
What group 2 has fewer protons than bromine but more protons than sulfur?
Calcium. Calcium has 20 protons, sulfur has 16, and bromine has 35.
What number is 16 more than its opposite?
the number 8 is 16 more than its opposite
Is selenium reactive?
yes, it is a non metal and it is placed on the right side of the Periodic Table, reactivity increases from left to right on the periodic table. since selenium is in group 16 out of 18 groups, it is a very reactive element. hope this helps you!
Can the GCF of 16 and 42 be more than 16?
