What are the only electrons that participate?
In most cases it is the valance electrons which participate in chemical reactions. Transition state elements are a major exception; they undergo reactions that involve the inner electron shells as well.
Elements on the right side of the periodict table with electrons sequentially filling the p orbitals of their valence shells are collectively known as the?
Elements on the right side of the periodic table with electrons sequentially filling the p orbitals of their valence shells are collectively known as the p-block elements. These elements include groups 13 to 18 (IIIA to VIIIA) on the periodic table.
What element has Five shells and 17 valance electrons?
Element 17's valence electron configuration is 3s23p5.
What group on the periodic table has the most stable amount of valence electrons?
That would be the Nobel gasses, 8A, because they have an octet of 8 electrons fully filling their valance shells so that they naturally do not react with other elements is either ionic or covalent bonding.
What does the group of the periodic have to do with reactivity?
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells

What element contains 7 electrons and 7 protons?
You should understand that while neutral atoms have the same number of protons and electrons, they do not usually have the same number of protons and valance electrons, because except for hydrogen and helium, atoms also have electrons in the inner shells, which are not valance electrons. Therefore, there is no atom which has 7 protons and 7 valance electrons, although there is an element that has 7 protons, and there are several elements that have 7 valence electrons.
How is the reactivity of elements related to valence electrons in atoms?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
What chemical family is composed of elements with filled valance shells?

How many valence shells does fluorine have?
flurine has atomic no. 9 so its electronic configaration is 2,7. Its valance shell has 7 electrons
Do noble gases have filled valance shells?
Almost always, yes. This is why they are so stable and do not react: having filled valance shells, they can neither give up or gain an electron to become more stable. The exception to this rule are the heavier noble gases, whose outermost valance shells are more prone to ionization due to the shielding effect from the electrons in the lower valance shells.
