The halogens have 5 electrons in the p sublevel.
Sb
iodine
Elements in the same column belong to the same family. The elements in the family also have the same number of valence electrons.
They belong to different families but HALOGENS family consists of diatomic molecular elements.
On the peroidic table of elements, the family tells you a brief overview of what kind of element it is. It could be a metal, or gas, and it usually describes what kind of metal (transition) or what kind of gas (noble).
Yes, separate electrons belong exclusively to a single atom. The only time that it doesn't is when the electrons are being shared by covalent or ionic bonding.
No. The atomic number of argon is 18. So it has 18 protons and 18 electrons (out of these, 8 electrons are valence electrons and belong to the outermost shell).
Elements which have their valency electrons in the p sub shell belong to this. Elements of groups 13,14,15,16,17,18 are in p block.
Such atoms belong to a group in the periodic table of elements.
The other elements relate to fluorine are chlorine, bromine , iodine etc since they have 7 valence electrons and hence, belong to group 17
The alkaline earth metals belong to group 2A elements. The alkali metals belong to group 1A elements. The halogens belong to group 7A elements. The noble gases belong to group 8A elements.
The halogens have seven valence electrons. The halogens are F, Cl, Br, I, and At. Fluorine
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.
Elements in the same column belong to the same family. The elements in the family also have the same number of valence electrons.
there are 7 electrons in the outer energy level of group 17 elements
