All halogen elements have 7 valence electrons (group 17): F, Cl, Br, I, At.
Chlorine.
Chlorine
Chlorine.
Neon has 0 valence electrons and so there cannot be any element with fewer valence electrons.
borin has more valence electrons than kernel electrons
Chlorine.
Chlorine
Chlorine.
there is no such element
Neon has 0 valence electrons and so there cannot be any element with fewer valence electrons.
Cl Chlorine
borin has more valence electrons than kernel electrons
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
A hydrogen only has one valence electron, while oxygen has 6.
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
Oxygen has six valence electrons, which means that it needs to gain two to become stable. it takes much more energy for oxygen to lose its 6 valence electrons than it would be to gain 2. When atoms form compounds, they become stable.
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
