- For example, hydrogen can occur in three isotopes: Hydrogen-1 (sometimes called protium) has one proton and no neutrons in its nucleus. (Notice that isotopes are named by separating the element name and the mass number with a dash). Hydrogen-2 (also called deuterium) has one proton and one neutron in its nucleus.

Measure of an Arc: Process & Practice Anyway, this is where we differentiate between an arc's measure and its length. The measure of an arc is the degree measurement of the angle that intercepts the arc. The measure of an arc is written as mAB. Notice that I said it's the degree measurement.

- Klinefelter syndrome, also known as the XXY condition, is a term used to describe males who have an extra X chromosome in most of their cells. Instead of having the usual XY chromosome pattern that most males have, these men have an XXY pattern. Klinefelter syndrome is named after Dr. Henry Klinefelter, who first described a group of symptoms found in some men with the extra X chromosome.

- Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among all the elements.n Earth it is relatively rare — 5.2 ppm by volume in the atmosphere. Most terrestrial helium present today is created by the natural radioactive decay of heavy radioactive elements (thorium and uranium, although there are other examples), as the alpha particles emitted by such decays consist of helium-4 nuclei.

MADMAN BIOLOGY Hydrogen and oxygen are elements. What that really means is that when an atom, the fundamental unit that makes up everything, has 1 proton (a positively charged sub-atomic particle) it is a hydrogen atom, and when it has 8 protons, it is an oxygen atom. Hydrogen gas is two hydrogen atoms bonded together, H 2.Oxygen gas is two oxygen atoms bonded together, O 2. Water, is one oxygen atom bonded to two different hydrogen atoms, H 2 O. When atoms are bonded together, (H 2, O 2, H 2 O etc.) we call the total structure a molecule.Hydrogen atoms and oxygen atoms are found in many different molecules, and these different molecules make up, solids, liquids, and gasses.ydrogen and oxygen are elements.

Atoms and elements When you combine two atoms of hydrogen with one atom of oxygen you get a water molecule H 2O. Like nitrogen, hydrogen can also be condensed to a liquid that freezes at – 259°C (-434°F) and boils at -252°C (-423°F). Hydrogen is one of the most common elements in our universe.The sun and many stars are made of hydrogen. It can also be found in the earth’s crust.very compound has certain features and a chemical formula. Water, for example, is a compound that has two hydrogen atoms and one oxygen atom in it. Its chemical formula is H 2O. When sodium (Na) combines with chlorine (Cl) you get a compound called salt (NaCl).

Deuterium Deuterium is a isotope of hydrogen which varies from hydrogen by one neutron normally hydrogen has only one proton, where as deuterium has one proton and one neutron. It has wide applications in fission reactors. The chemical symbol of deuterium is 2H and is denoted by  D .hese are hydrogen with zero neutrons, deuterium contains one neutron, and tritium contains two neutrons. Here we are discussing about the isotope of hydrogen that is deuterium which is known as heavy hydrogen. How this isotope is useful, what is its mass and other properties, let’s discuss about that.

- The electron energies in the hydrogen atom do nor depend on the quantum numbers m and l which characterize the dependence of the wave function on the angles θ and φ. The allowed energies are. En = -me4/(2ħ2n2) = -13.6 eV/n2. Here n is called the principle quantum number. The values En are the possible value for the total electron energy (kinetic and potential energy) in the hydrogen atom. The average potential energy is -me4/(ħ2n2) and the average kinetic energy is me4/(2ħ2n2).
