All chemical reactions.
The three factors determine the chemical properties of an element:The number and arrangement of electrons in an atomThe number of valence electronsThe number and arrangement of electrons
The valence is determined experimentally.
ELEMENT
the number of valence electrons determine the reactivity of the atoms
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
Chemical properties of an element determine by the number of electron
Valence Electrons
The number of electrons of both atoms and its valence number.
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
In the neutral atom of a chemical element number of electrons= number of protons=atomic number.
they determine the difference between the elements like a hydrogen atom has 1 electron and carbon has 6
Valence shell electrons or valence electrons determine the chemical properties of an atom...
