Group I (alkali metals) and Group II (alkaline earth metals) elements on the Periodic Table are more likely to give away electrons to form positive ions. These elements have one or two electrons in their outermost energy level, making it easier for them to lose these electrons and achieve a stable electron configuration.

What is a group of elements in the periodic table?
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
What is a group in the peirodic table?
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outermost energy level (valence electrons). There are 18 groups in the periodic table, each denoted by a number and/or letter indicating the number of valence electrons for the elements in that group.
How would you find valence electrons in a periodic table?
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
What group in the periodic table has two valence electrons in their atoms?
Group 2 in the periodic table (alkaline earth metals) has two valence electrons in their atoms. Examples of elements in this group include beryllium, magnesium, calcium, and strontium.
Where are the elements that have the same valence electrons found in the periodic table?
Elements with the same number of valence electrons are found in the same group or column of the periodic table. For example, all elements in Group 1 (such as lithium, sodium, potassium) have 1 valence electron.
What group on the periodic table gains two electrons?
Group 16 elements.
What is a group in the periodic table called?
A group in the periodic table is a vertical column of elements with similar properties due to their shared number of valence electrons. Groups are also known as families.
What is the group of elements in periodic table with eight electrons?
group 18, noble gases
What is the columns of elements on the periodic table which have the same number of valence electrons and share many patterns?
For example the elements from the group 1 of the periodic table.
What is a colunm in the periodic table?
A column in the periodic table is called a group or a family. Elements within the same group share similar chemical properties due to having the same number of valence electrons. There are 18 groups in the periodic table.
Why are group a elements on the periodic table called representative elements?
They follow a pattern for valence electrons.
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
What is a group of elements in the periodic table?
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
What is the number of valence electron for all the elements in periodic table group 2A 2?
Elements in group 2A of the periodic table have two valence electrons. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium.
A verticle column in the periodic table?
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
What do all elements shahre within each group in the periodic table?
elements in a group have the same number of valence electrons
What is a group in the peirodic table?
