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.
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 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.
What is the octet rulewhich element is the exception?
Some elements that are known to violate the octet rule are: Hydrogen, Helium and Lithium (two electrons) Aluminum and Boron (less than octet but will form an octet if possible), Period 3 elements with p orbitals (more than an octet using empty d orbitals), noble gas compounds (more than an octet), and elements like nitrogen with an odd number of electrons (form free radicals when octets are not possible).
What is odd helium hydrogen neon or argon?
Helium and neon are odd elements because they have an odd number of protons in their nucleus. Hydrogen and argon are even elements because they have an even number of protons.

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 makes calcium unstable?
calcium is not stable because the outer most atomic level is not full the only elements that are stable are the nobel gasses(helium,neon,argon,krypton,xenon,and radon)
What is the odd one out lithium nitrogen oxygen carbon?

Why is hydrogen the odd one out?
Hydrogen is often considered the odd one out because it does not fit neatly into any specific group in the periodic table. It has unique properties that differentiate it from other elements, such as being the only element that can exist in three different isotopic forms (protium, deuterium, tritium). Additionally, hydrogen has a unique electron configuration and displays both metal and non-metal properties.
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
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
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?
