Does helium have the same amount of valence electrons as the others in its group?

No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.

What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
How does helium differ from the other elements in its family noble gases?
It differs because it only has 2 electrons in its valence shell, and all the other noble gases have 8 electrons.
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 is odd element in noble gases?
The odd element in the noble gases is Radon. This is because it is radioactive, and all the others are highly unreactive.
Why is the noble gas group the most stable group?
According to the Octet Rule, the most valence electrons any atom can have is 8. Atoms naturally want to meet this rule either by losing or gaining enough electrons to have a total of 8 valence electrons. The nobel gases have exactly 8 valence electrons. The neither need to lose or gain any and therefore do not play well with others. The losing or gaining of valence electrons determines the stability and reactivity of the element.

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.
Is helium more reactive that magnesium?
No, helium is a noble gas, meaning it has a full outer electron shell. It does not need to gain or lose electrons to become stable, so it is almost completely inert. Hydrogen on the other hand, is extremely reactive as it only needs one electron to become stable. This is why the Hindenburg airship exploded, and why we use helium in similar craft today.
Which of the following would not have the same number of valence electrons as the others boron aluminum gallium selenium?
Selenium
Why are the valence electrons of an atom the only electrons likely to be involved in bonding to other atoms?
It is because only certain (the outer) electrons are available for chemical bonding that they are called valence electrons. By definition, the electrons available for bonding are called valence electrons. The others are more tightly bound to the nucleus.
