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 the scientific name for helium?
Helium doesn't have a "common name" as such. We call this inert gas helium, and nothing else. A link can be found below for more information in the odd noble gas.
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.
What has 2 electrons and 2 protons?
The atomic number of an element tells us that atom's number of protons. If the atom is neutral, its number of protons is going to equal its number of electrons. Thus, we need only find the element with the atomic number of 2, which is helium.
If 9.0g of water contain 1.0g of hydrogen what mass of oxygen is contained in 36g of water?
What an odd question. Well, whatever. The question shows that 1/9 of the solution is hydrogen. So it must be said that 8/9 is water (assuming the sample comprises solely of hydrogen and water)36/9 = 44 x 8 = 32So 32g of it is oxygen.
What is odd helium hydrogen neon or argon?
neon
What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
Can two isotopes of different elements have the same mass number?
Yes, as an example carbon-14 and nitrogen-14 are two isotopes of different elements with the same mass number. Other examples include hydrogen-3 and helium-3, argon-40, calcium-40, and potassium-40 iron-58 and nickel-58 are both stable isotopes. Potassium-40 is an interesting radioisotope that decays to argon-40 by beta decay. This decay path is used to put dates on ancient objects. Calcium-40 is a stable isotope. Hydrogen-3 emits a beta particle and thence decays to helium-3. Helium-3 is the only nontrivial stable isotope that has fewer neutrons than it has protons. Nitrogen-14 is the most common isotope in the Universe that has and odd number of protons and an odd number of neutrons. It is more common than hydrogen-2 or lithium-6. Beryllium-9 is the only stable isotope of an element -- that only has one stable isotope -- that has an even number of protons (4) and an odd number of neutrons (5).

What is the odd one out lithium nitrogen oxygen carbon?
what is the odd one lithium, nitrogen , oxygen , carbon
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 hydrogen the odd one out?
because its a loser and has no friends because he was beat up in highschool.
Two elements that form compounds that can be exceptions to the octet rule?
Boron and fluorine in the trivalent boron compound BF3 have only 6 electrons in the valence shell.Oxygen and nitrogen in nitric oxide, NO, contain one or more atoms which have an odd number (one UNpaired '.' ) of electrons. Lewis dot structure |N.=O

What type of gas can make your voice deeper?
Anti-Helium as far as I know. Why do you ask? Is it because you're Justin Bieber and really NEED a deeper voice? Or some other odd reason?
Will the sum of three odd numbers be even or odd?
odd. odd=odd odd+odd=even odd+odd+odd=odd it keeps alternating in that fashion
Why does Hydrogen not follow the octet rule?
Because it has an atomic mass of only 1.
