Taking the second electron from alkali metals is difficult due to their low effective nuclear charge and the resulting electron shielding. Alkali metals have only one valence electron, which is loosely bound and easily removed. Once this electron is lost, the resulting cation has a full outer electron shell, leading to increased stability and a stronger attraction between the remaining electrons and the nucleus, making it energetically unfavorable to remove a second electron. Additionally, the increased repulsion between the remaining electrons further complicates the process.
What else can I help you with?
Why alkali metals do not show 2 oxidation state?
Because they have only one electron in their valency shell. The second oxidation state would require the atom to lose an electron from its penultimate shell which is full.
Are alkali metals the first or second group?
First group
What is the metal in the second period with one outer electron?
The metal in the second period with one outer electron is lithium (Li). It is located in Group 1 of the periodic table, which consists of alkali metals. Lithium has an atomic number of 3 and is known for its light weight and use in batteries.
What is the group number of alkali earth metals?
The group number of alkali earth metals is group 2 on the periodic table. These metals include beryllium, magnesium, calcium, strontium, barium, and radium. They are located in the second column from the left on the periodic table.
What is alkali metals and alkali earth metals?
Alkali metals are in the first column of the periodic table, but do not include Hydrogen. The alkali metal family is composed of Lithium, Sodium, Potassium, Rubidium, Cesium and Francium. An example of an alkali metal is Sodium (Na).

Are alkali metals the first or second group?
First group
What are the elements called in the first group of the periodic table that have one outer shell electron and is extremely reactive?
Oh, dude, those are the alkali metals. They're like the divas of the periodic table with their one outer shell electron, always causing drama and reacting with everything in sight. You definitely don't want to mess with those guys unless you're ready for some serious fireworks!

The metal in the second period with one outer electron is lithium (Li). It is located in Group 1 of the periodic table, which consists of alkali metals. Lithium has an atomic number of 3 and is known for its light weight and use in batteries.

The group number of alkali earth metals is group 2 on the periodic table. These metals include beryllium, magnesium, calcium, strontium, barium, and radium. They are located in the second column from the left on the periodic table.

Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
Where are the most active elements located on periodic table called?
The most active elements on the periodic table are located in Group 1, also known as the alkali metals. These elements are highly reactive due to their tendency to lose their outermost electron to achieve a stable electron configuration.
What do alkali metals react vigorously with?
An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.
Where are the alkali metals and the halogens located on the periodic table?
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
What is in the second column of the periodic table?
Alkaline earth metals are placed in second column. The elements have 2 valence electrons.
What groups are alkaline earth metals and the alkali metals in?
the first and second groups. alkaline earth metals: group IIA (2) [It consists with "Be,Mg,Ca,Sr,Ba,Ra"] alkali metals: group IA (1) [It consists with "Li,Na,K,Rb,Cs,Fr"]
