What else can I help you with?
Do all noble gases have eight valence electrons?
Yes, except for helium which only two electrons. All noble gases are found under the noble gas family to the far right of the periodic table.
What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
How does helium differ from the other elements in its family noble gases?
Helium differs from other noble gases in its smaller atomic size and lower atomic mass. It is also the only noble gas that does not have a full shell of electrons, containing just 2 electrons in its outer shell. Additionally, helium is the least reactive of the noble gases due to its stable electron configuration.
What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
What is odd element in noble gases?
The odd element in the noble gases is xenon (Xe). It has an odd number of protons and neutrons in its nucleus, unlike the other noble gases (helium, neon, argon, krypton, radon) which have an even number.

Which of the following would not have the same number of valence electrons as the others boron aluminum gallium selenium?
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.

What do the noble gases have in commmon?
All noble gases have completely filled valence orbitals. Helium has 2 valence electrons, the others have 8. They are stable configurations and as such noble gases are generally chemically inert at standard temperature and pressure.
How many electrons are in the valence shells of group 1?
There are 2 electrons in the first valence shell ("orbital"). The first orbital is an "s" orbital. If the atom is neutral in charge and there is only 1 electron - you have Hydrogen. If the atom is neutral in charge and you have only 2 electrons - you have Helium. Since the outermost shell of electrons is full, considerable chemical stability is conferred to the Helium atom, thus it is a member of the "Noble Gases" - those that have full comlpements of electrons in their outer shells, the others being Neon, Argon, Krypton, Xenon, and Radon.
Does noble gases have less stable electronic configurations than others?
No. Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
How do you count the valence electrons of an atom?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Why do atoms form positive ions and others form negative ions?
It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
How do the valence electrons tell about the reactions of different elements?
Not sure if I understand your question correctly, but some elements are more electronegative than others, so they draw in electrons better than others. For example, in NaCl, chlorine (Cl) is much more electronegative than sodium (Na) so it simply takes the sodium's extra valence electron.
