Alkali metals, which belong to Group 1 of the Periodic Table, have one valence electron and are characterized by having a single electron in their outermost energy level. The number of energy levels increases as you move down the group; for example, lithium (Li) has 2 energy levels, sodium (Na) has 3, potassium (K) has 4, rubidium (Rb) has 5, cesium (Cs) has 6, and francium (Fr) has 7. Thus, the number of energy levels for alkali metals ranges from 2 to 7, depending on the element.
What else can I help you with?
How many electrons do alkali metal family have?
they all have a differnet number of electrons, but all have a charge of 1-
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
How many electrons do the alkali metals have in their outer energy shell?
If you are referring to the alkali metals of Group 1, such as sodium and potassium, the answer is no - in fact with a valence of 1 they are short 7 electrons in their outer level, which is why they react so readily (and violently) with the halogens, chlorine, fluorine and so on.
Do transition have higher melting point than alkaline and alkali metals?
Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.
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 the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
How many electrons do alkali metal family have?
they all have a differnet number of electrons, but all have a charge of 1-
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?

What is groups 1 and 2 in the periodic table called?
Group 1 in the periodic table is called the alkali metals, and Group 2 is called the alkaline earth metals. These groups of elements share similar chemical properties due to the number of electrons in their outermost energy level.
What is the group of elements with the same number of valence electrons?
Elements in the same group on the periodic table have the same number of valence electrons. Valence electrons are the electrons in the outermost energy level of an atom and determine an element's chemical properties.
What chemical family has a group number 1A?
This is the alkali metals family.
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 the group number for francium?
Francium is in the group 1 (alkali metals) of the periodic table.
