What else can I help you with?
what elements have equal numbers of electrons and valence electrons?
hydrogen and helium
How are the elements within row different?
They have different numbers of valence electrons.
How many valence electrons do transitions elements have?
How many valence electrons do transition elements have?
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).
How many electrons does an atom need to a outer energy level?
There are different numbers of valence electrons in different elements.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Do elements in the same group have similar atomic numbers?
Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
How do you find the valence of an element?
elements, or atoms, do not have valence numbers, they have valence orbitals (the outermost one) or valence electrons (all the electrons in the outermost orbital). you can look this up anywhere that shows the electron configuration, like your periodic table.
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.
