Valence electrons are responsible for chemical boding.
Valence shell electrons or valence electrons determine the chemical properties of an atom...
Valence electrons are very important for the chemical properties of chemical elements; but all electrons have identical sizes.
The valence electrons influence many properties and characteristics of a material. The properties of a material which are influenced by the valence electrons are chemical properties, electrical conductivity, some mechanical properties, the nature of inter atomic bonding, atom size, and optical characteristics.
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
The valence electrons
The valence electrons of an element are mainly what determine an element's properties.
Chemical properties of an element determine by the number of electron
protons and valence electrons
Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
One of the properties of metals is their tendency to lose valence electrons, in order for another metal to have complete valence electrons.
This is rightThe outermost electrons account for many of the physical and chemical properties of elements.
