A molecule this is short of hydrogen atoms and has a double bond is H2CCH-. The Lewis structure would be Two H's bonded to a C atom, double bonded to another C atom single bonded to one H. The second C atom has a -1 formal charge.

∙ 15y agoFor carbon a chain with double bonds is known as an alkene ex. C-C=C-C is "2-butene". Also for carbon a C=C part of a chain can be called a unit of unsaturation.

What is in a atom of propane?
An atom of propane is a hydrocarbon of the alkane group, it's chemical formula is C4H10, it is a short chain molecule as it only has 4 atoms of carbon in its molecule.
What is the symbol of water?
Strictly, only elements have chemical "symbols". Compounds such as water have chemical formulas, and the one for water is H2O.
What is the difference between a chemical symbol and a chemical formula?
The chemical symbol is used only for chemical elements; the chemical formula is for molecules. Ex.: Na is the chemical symbol of sodium and NaCl is the chemical formula of sodium chloride.
What type of bond is characterized by sharing two pairs of electrons?
Such a bond is called covalent bond.A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds. In short, the attraction-to-repulsion stability that forms between atoms when they share electrons is known as covalent bonding.Covalent bonding includes many kinds of interaction, including σ-bonding, π-bonding, metal to metal bonding,In the molecule H2, the hydrogen atoms share the two electrons via covalent bonding
A polar covalent bond forms when are not shared equally between atoms?
Essentially yes; when the electrons are unevenly spaced, one atom will become more positivethan the other in a covalent bond. But there's a little bit more to it than just that:Covalent molecules are made polar when there is a difference in electronegativity between the atoms involved.Electronegativity is, in short, the atom's ability to attract electrons to it. Something with high electronegativity will be able to attract electrons more easily than something with low electronegativity.For example: Hydrogen is a lot less electronegative than Fluorine, so in the instance of Hydrogen Fluoride (HF) the H would be delta positive and the F would be delta negative.In this case the electrons being shared between the two elements would be more attracted towards the fluorineatom than the hydrogen because of the higher electronegativity of the F atom.This would make the molecule polar.HOWEVER!An important fact to remember is that when a polar covalent molecule is in proximity to another molecule, it is intermolecular (dipole-dipole or Hydrogen normally) bonds that are created. This means that the forcethat the polarity of the molecule is actually affecting, is the force between one molecule of (in the example I used) HF and another molecule of HF closest to it.A covalent bond is a covalent bond either way, it is the molecule that becomes polar due to a difference in electronegativity.
What is a molecule that is short of hydrogen atoms and has a double bond called?
This referes to unsaturated (organic) compounds, e.g. alkenes
Why does H2 molecules exist when He2 does not?
H2 technically does contain molecules. Or at least, molecule. H2 is two hydrogens covalently bonded, so that the lowest energy level is filled. Since H2 has two atoms (hydrogen and hydrogen), it is not an element, because there is more than one atom. H2 is a molecule itself. However, in context of nature, it is rare that you would ever find an H2 molecule on its own unless you were working with one in a laboratory. So, if you were considering the whole of an H2 gas, there would be many molecules of H2. Short answer: H2 is a molecule itself. Many H2 means there are many molecules of H2.
What is short for carbon dioxide?
CO2, (note 2 is subscript and denotes that there is 2 oxygen atoms in the molecule.)
What has the author W Lakin written?
W. Lakin has written: 'Short range anti-correlation of electrons in the hydrogen molecule' 'Shor t range anti-correlation of electrons in the hydrogen molecule' -- subject(s): Accessible book
When are hydrogen bonds formed?
Short Answer: a partially positive hydrogen atom gets attracted to a partially negatively charged atom. _______________________ Take water for example. There is an Oxygen atom (which pulls electrons towards it-- making it partially negative) There are also two hydrogen atoms. The (negatively charged) electron on each H atom is being pulled towards the O atom, making the Hydrogen partially positive. Now, when two water molecules come together, the partially positively charged H's on one water molecule are attracted to the partially negatively charged O's on the other molecule. This attraction between oppositely charged atoms on different molecules creates a 'hydrogen bond'.

How any atoms are in C2HO2?
2 of carbon, 1 of hydrogen, and 2 of oxygen. So well, 5. IN SHORT: 5.
What is formed when atoms of one element are combined with atoms of other elements?
A compound is formed. The most known about compound is obviously water. This is where 2 Hydrogen atoms combine with that of 1 Oxygen atom giving us H2O. Not all combinations are possible though, due to them still being unstable and wanting to gain or lose electrons while attached to the others, changing the chemical composition to another as it connects to more atoms.
Does gravity make the sun's heat and light?
Yes. The sun is often cited as an example of energy from fusion of hydrogen atoms into helium. You might consider then that this is "simple" physical chemical reaction between these atoms. However hydrogen does not combine to make helium under normal conditions. What it takes is that the hydrogen atoms are squeezed together by the massive gravity of the sun until the nucleus of each atoms essentially touch and unite to form hydrogen and release energy in the process. In short the Sun is able to convert energy from gravity into light.
What is the short form of hydrogen?
short form of Hydrogen is = H.
What does desaturated mean?
The short answer is desaturated is when you mix any color with white. If you mean 'unsaturated' - that refers to the fact that carbon atoms in food have room for extra hydrogen atoms to be added.
