What chemical families are very reactive?

What chemical families are very reactive?

The two most reactive families of elements are the halogens and the alkali metals.

Which chemical is most reactive?

fluorine
The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal (and most expensive element).

What chemical family contains the most reactive nonmetals?

The halogens
The halogens are the most reactive elements; especially fluorine.

What family is the least reactive?

Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.

Which two families are highly reactive and why?

Group 1: Hydrogen and Alkali Metals

• All the elements in group 1 have just one valence electron, so they are highly reactive.
• All the other elements in group 1 are alkali metals.
• The alkaline Earth metals include all the elements in group 2 (see Figure below).

What family is the most reactive and why?

The family that contains the most reactive metals are the alkali metals.

What groups are most reactive?

The most reactive metals are the elements in Groups 1 and 2. Elements in Group 1 generally lose an electron so their outer energy level is empty. Elements in Group 2 generally lose two electrons so their outer energy level is empty. These groups easily give up their valence electrons to make a compound.

What group is the most reactive?

Reactivity of Group 1 Elements Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Which group elements are highly reactive?

The two most reactive groups of elements are the alkali metals and the halogens because of their valence electrons.

Which family is the most stable?

Noble Gases make up the most stable elements on the Periodic Table. All elements in this group have 8 electrons in their outer shell, making it hard for any of them to form compounds with other elements they come in contact with.

Which is the most reactive group of elements?

The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.

How are alkali metals similar to other chemical families?

The chemical families consist of elements that have the same valence electron configuration and tend to have similar chemistry. The alkali metals (group 1) have ns 1 valence electron configurations and form M + ions, while the alkaline earth metals (group 2) have ns 2 valence electron configurations and form M 2+ ions.

Which is the heaviest element in the family?

In fact, the chemistry of these elements is almost exclusively characterized by +3. Only the heaviest element (Tl) has extensive chemistry in the +1 oxidation state. It loses the single 6 p electron to produce TlX monohalides and the oxide Tl 2 O.

Which is more reactive radium or beryllium?

Beryllium is relatively unreactive but forms many covalent compounds, whereas the other group members are much more reactive metals and form ionic compounds. As is the case with the alkali metals, the heaviest element, radium, is highly radioactive, making its size difficult to measure.
