Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
What differientiates metallic and non-metallic elements on the periodic table at a subatomic level?
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.
Do each of the elements in Group 1 have the same or different numbers of electrons?
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
What are electrons on a periodic table?
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons
What is a elements oxidation number?
A neutral atom has an oxidation number of 0. An anion has a negative oxidation number. The oxidation number of a cation is positive.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
What differientiates metallic and non-metallic elements on the periodic table at a subatomic level?
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.
Will chlorine gain number of electrons gained or lost?
Chlorine gain electrons.
What is the number of electrons gained or lost in chlorine?
+1
What is the number of electrons gained or lost in Fluorine?
80
Do each of the elements in Group 1 have the same or different numbers of electrons?
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
Can some elements have the same number of electrons in their outermost level?
Elements in the same group have the same number of valence electrons.
Can you form ions of the same element by changing the number of protons?
No. As the number of protons changes, the identity of the element changes and new elements are formed.Ions are formed only when electrons (and not protons) are gained or lost.
Elements that have the same number of valence electrons are?
All elements in the same group have the same number of valence electrons.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
