What else can I help you with?
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).
How many elements are in group 1 on the periodic table?
These six elements are Li, Na, K, Rb, Cs and Fr.
What are the atomic numbers of the first three elements in Group 1?
1 H Hydrogen3 Li Lithium11 Na Sodium
Which elements are the alkali metals?
The metals in the far left column of the periodic table are the alkali metals. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is one of the elements of group 1 of the periodic table?
Some people disagree on whether hydrogen is in group 1, but the elements in group 1 are Li (lithium), Na (sodium), K (potassium), Rb (Rubidium), Cs (caesium), and Fr (francium). These are the ones that react violently with water, with Li giving the weakest and Fr the strongest reaction. Hope that helps :)
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).
What element does Na resemble?
Na (sodium) closely resembles lithium (Li) as both elements belong to the same group on the periodic table and share similar chemical properties such as reactivity and the ability to form compounds with other elements.
What Group 1A elements is the most reactive cs Li K Na?
K
What two elements that belong to the same group?
Two elements that belong to the same group are sodium (Na) and potassium (K), which both belong to Group 1 (also known as the alkali metals) on the periodic table.
What group of elements forms 1 cations?
Alkali metals, Li Na K etc
What are group 1 elements?
The alkali metals are: Li, Na, K, Rb, Cs, Fr.
How many elements are in group 1 on the periodic table?
These six elements are Li, Na, K, Rb, Cs and Fr.
An element in group 1 of the periodic table?
Elements in Group 1 include, Li, Na, K, Rb, Cs, Fr
Which elements are apart of sodiums family in the periodic table?
Sodium, Na, is in group 1 on the periodic table. The elements in group1 are the elements in that vertical column, which are Li,Na,K,Rb,Cs,Fr.
What does Li Na and K have in common?
Lithium, sodium and potassium are all group I elements. They are also called alkali metals. They react violently with water to form strongly alkaline solutions. The elements, as we descend the group in the periodic table, become increasingly reactive.Li Na K are alkali metals. They are present in group-1. They have one valence electron.All of these elements are located in group 1 of the periodic table. Each of these elements are highly reactive metals. They react with acids to produce salts. All of these are good conductors of electricity and heat.Li,Na and K are in the 1st group of the periodic table. They are alkaline metals. They all have a valency of 1.
What are the atomic numbers of the first three elements in Group 1?
1 H Hydrogen3 Li Lithium11 Na Sodium
What pair of elements has the most similar chemical properties?
The pair of elements with the most similar chemical properties are lithium (Li) and sodium (Na). They belong to the same group in the periodic table (Group 1) and exhibit similar reactivity and chemical behavior due to having one valence electron.
