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).
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 do the atoms in the same column on the periodic table have in common?
Group 1a in periodic table contains hydrogen and the alkali metals. the question does not specify which three out of the seven elements in the group are being referred to. The metals all ionise to form M+ ions e.g. Li+, Na+, K+ etc. Hydrogen is the odd one out- whilst it does lose an electron to form H+ (a bare nucleus with a charge of +1) it can also gain an electron (to achieve the noble gas configuration of He, helium) forming the H- hydride ion.
How many neutrons does the neutral atom have?
It varies depending on the atom but basically there are the same number of neutrons as there are protons. Helium has two protons, two electrons, and two neutrons. The difference between the atomic mass and the atomic number equals the atom's number of neutrons. Consider hydrogen, for example. Standard hydrogen has no neutrons, just one proton. Deuterium is an isotope of hydrogen with one neutron, and tritium (which is unstable) has two neutrons. Carbon 12 has six protons and six neutrons, but carbon 14 (which is unstable) has six protons and eight neutrons. As you move up the periodic table, nuclei tend to have more neutrons than protons. 92 U 238, for example, has 146 neutrons.
Which is the odd one out helium argon hydrogen kryton?
Hydrogen is odd one as it is in group 1. The other elements are in group 18 (noble gases).
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 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.

What doesn't belong sulfur water neon carbon?
Water its a chemicl compound Other possible odd ones out are:- Neon is a gas at normal temp and pressure none of the others are Water is a liquid at normal temp and pressure, none of the others are
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.
Why doesn't potassium bond with neon to form a compound?
Helium is considered a stable element (you can tell because it is a Nobel gas, in group VIII of the Periodic Table), as it has a full compliment of electrons in its energy level. Ionic bonds will only be formed when a metal and a non-metal lose/gain electrons and become stable as a compound. There is no point in helium losing or gaining electrons with other elements because it's already stable.
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?
