Two highly reactive elements in period 2 are the metal lithium and what?
The other highly reactive element in period 2 is fluorine, a non-metal. Both lithium and fluorine readily form compounds due to their high reactivity.
Is table salt made up of metals or gases?
No. Table salt is composed of two elements which are, in their elemental state under "ordinary" circumstances (STP), a highly reactive metal and a highly reactive poisonous gas.
If you mix chlorine lithium and nickel together which two elements would be the most reactive?
Chlorine and lithium would be the most reactive because chlorine is a halogen and lithium is an alkali metal, both of which are highly reactive elements. Nickel is a transition metal and is less reactive compared to chlorine and lithium.
Are group 2 elements highly reactive?
Group 2 elements are moderately reactive. They are less reactive than Group 1 elements but more reactive than Group 3 elements. They readily lose two electrons to form 2+ cations in reactions.
What is an element that is highly reactive gaseous nonmetal?
Fluorine is a highly reactive gaseous nonmetal element. It is the most reactive nonmetal on the periodic table and readily forms compounds with other elements.
What are two similarities and differences between the elements sodium and oxygen?
Similarities: Both sodium and oxygen are essential elements found in the periodic table. Both elements are reactive, with sodium being a highly reactive metal and oxygen being a reactive nonmetal. Differences: Sodium is a metal, while oxygen is a nonmetal. Sodium is a solid at room temperature, while oxygen is a gas.
Why do the elements in group one and two of the periodic table react o easily?
It is the s block. they are reactivated generally.
A group of element that has 2 valene electrons are called what?
A group of elements with two valence electrons are called alkaline earth metals. This group includes elements like magnesium and calcium. These elements are highly reactive due to their tendency to lose their two valence electrons.
A family of elements that has two electrons in its outer energy level is?
The family of elements with two electrons in its outer energy level is the alkaline earth metals. This group includes elements like beryllium, magnesium, calcium, strontium, and barium. These elements are highly reactive and tend to form 2+ cations by losing their two outer electrons.
How many elements in the first period?
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
Name two most reactive elements in the group alkali metals?
These elements are francium and lithium.
Which column contains the most reactive elements?
The column that contains the most reactive elements is the alkali metals column, which is the first column in the periodic table. Alkali metals are highly reactive due to having only one electron in their outer shell, making them eager to lose this electron and form positive ions.
