the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
The number of valence electrons of an element is determined by its Periodic Table group in which the element is categorized. Except for groups 3 to 12 which are the transition metals.
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
Well, to keep it simple, the number of electrons is usually the number of protons in the element, which is the atomic number. For instance, hydrogen has 1 proton and 1 electron, while Lead, Pb, has 82 protons and electrons. This is, of course, when the elements are naturally occuring. There are isotopes for elements which change the number of protons or electrons, thus changing the charge.
Elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
Chemical properties of an element determine by the number of electron
4.See the Related Questions for how to determine the number of electrons in the outermost shell of all the elements!
The group number determines the number of valent electrons. For example, the elements in the group 5 have 5 valent electrons.
they determine the difference between the elements like a hydrogen atom has 1 electron and carbon has 6
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
Because groups/families determine how many valence electrons the element will have. Therefore, all the elements in a group/family have the same number of valence electrons Chemimal and Physical.
the atomic masses and atomic numbers... group number and period number... valence electrons and number of shells... these all determine the chemical properties of elements...
Number of protons PLUS number of valence electrons (plus - if needed - number of electrons in inner shell).
Chemical properties of an element determine by the number of electron
They don'tThey group elements with the same number of valence electrons.The valence electrons of an element determine how that element bond and how many bonds it forms.So elements with the same number of valence electrons tend to have similar chemical properties.

it depends on which element it is, all elements have a different number of electrons unless ions come into play, then you will have to look at the number of protons to determine it's identity
