Valance level
Elements are placed in the periodic table based on their electronic configuration, which refers to the arrangement of electrons in the atom's energy levels or orbitals. Elements with similar electronic configurations are placed in the same column or group of the periodic table. The periodic table organizes elements in order of increasing atomic number and arranges them into rows and columns based on their electronic structure.
Elements arranged in one column exhibit similar chemical properties. Elements in same column also have similar physical properties. Also elements in same column has similar electronic configuration.
This is probably a reference to the periodic table of the elements, which has columns. All the elements in a given column have the same configuration of valance electrons. There is a column of noble gases, a column of halogens, etc.
The column in the periodic table that contains atoms with an ideal electron configuration is the noble gases group (Group 18). These atoms have a full outer shell of electrons, making them stable and less likely to react with other elements.
No, Noble Gases have the stabliest configuration on the periodic table because they follow the octete rule by having eight electrons. They can be found on the far right column.
The electron configuration in the outer shell is the same for all of the elements in the same column. This results in some similar chemical properties between these elements in the same group (column).
In the Mendeleev periodic table, elements in each column had similar chemical properties because they shared the same valence electron configuration. This allowed for elements within the same group to exhibit similar reactivity and form similar compounds.
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.
Elements in the same vertical column or group have similar valence shell electronic configurations,the same number of electrons in the outer orbitals, and similar properties.
Elements in the same column on the periodic table have similar chemical reactivity because they have the same outer electron configuration and it is the electron structure that determines an elements properties.
These elements - fluorine, chlorine, bromine, and iodine - are part of the same column of the periodic table called the halogens. Halogens are highly reactive nonmetal elements that share similar chemical properties due to their outer electron configuration.
The vertical column in the periodic table is called a group or a family. Elements within the same group share similar chemical properties due to their similar electronic configurations.
