elements of girst group are called alkali metals
Wiki User
∙ 11y ago
The first group of the Periodic Table consists of alkali metals, which include lithium, sodium, potassium, rubidium, cesium, and francium. These elements have one electron in their outer shell and are highly reactive. They are soft and silvery in appearance.

What are elements in the first group of period table called?
alkali metals
What are the elements in the first group that have one outer shell electron and that are very reactive called?
The elements in the first group with one outer shell electron and high reactivity are called alkali metals. This group includes elements such as lithium, sodium, and potassium. Alkali metals readily lose their outer electron to form positive ions in chemical reactions.
Is alkali metals a group 1 elements?
Yes, alkali metals are group 1 elements because they belong to the first group of the periodic table and share similar chemical properties such as forming hydroxides when reacting with water.
Alkali metals are the elements in the what column?
Alkali metals are the elements in the first column of the periodic table, also known as Group 1. This group includes elements such as lithium, sodium, and potassium. Alkali metals are highly reactive and exhibit similar chemical properties due to their single outer electron configuration.
What elements have more predictable properties main group elements or transition elements?
main group elements
Oxidation number for first 20 elements?
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
What are elements in the first group of period table called?
alkali metals
What Elements on the left side of the table are classified as what type of elements?
Elements on the left side of the periodic table are classified as metals. These elements tend to have high electrical conductivity, luster, and malleability, and are typically solid at room temperature.
How do you discriminating cation in the same group?
why the first elements and eighth elements shows similar properties
What elements are in the first group in the periodic table?
alkali metals
How did group 14 of elements get his name?
Group 14 is known as carbon family as the first element in the group is carbon.
Which group of the periodic table has the elements with lowest first ionization energies?
The group with the elements that have the lowest first ionization energies is Group 1, also known as the alkali metals. This group includes elements such as lithium, sodium, and potassium, which have one valence electron that is easily removed to form a positive ion.
How is boron different from other elements in group 13?
Boron is the only element in group 13 that is a metalloid, meaning it shares properties of both metals and nonmetals. It has a unique structure due to its small atomic size and high ionization energy compared to its group members. Boron also forms covalent compounds instead of ionic compounds like other group 13 elements.
If you were looking for a very reactive atom would you look in group 1 or 18?
You would look for a very reactive atom in group 1, also known as the alkali metals. These elements have one electron in their outermost shell, making them highly reactive as they easily lose this electron to form positive ions. Group 18, on the other hand, consists of the noble gases which are highly stable and unreactive due to having a full outer shell of electrons.
What two characteristics of the elements in the first group?
Hydrogen & Lithium 😄
What are the elements in the first group that have one outer shell electron and that are very reactive called?
The elements in the first group with one outer shell electron and high reactivity are called alkali metals. This group includes elements such as lithium, sodium, and potassium. Alkali metals readily lose their outer electron to form positive ions in chemical reactions.
What is the first family on the periodic table of elements?
The first family (Group 1) are the alkali metals.
