How come 1 hydrogen is positive and two bonded hydrogens are neutral?

Hydrogen has a valency of one, meaning that a lone hydrogen atom is looking to pair up with one other atom of something-or-other; until it does, it has a positive electrical charge, but once that atom has paired up with another hydrogen atom (which will have also had a positive charge) the valency of both is satisfied, & so the bonded pair become neutral.

Why do hydrogen bonds occur in water?
A hydrogen bond is a special type of dipole-dipole force that exists between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This type of force always involves a hydrogen atom and the energy of this attraction is close to that of weak covalent bonds (155 kJ/mol), thus the name - Hydrogen Bonding. These attractions can occur between molecules (intermolecularly), or within different parts of a single molecule (intramolecularly).[2] The hydrogen bond is a very strong fixed dipole-dipole van der Waals-Keesom force, but weaker than covalent, ionic and metallic bonds. The hydrogen bond is somewhere between a covalent bond and an electrostatic intermolecular attraction.
Can CH4 for hydrogen bond?
No, in CH3F all the hydrogen atoms are bonded to carbon, which is not very electronegative. In order to form hydrogen bonds a molecule must have hydrogen bonded directly to ahifhly electronegative element such as nitrogen, oxygen, or fluorine.
Structure model of hydrogen gas?
H2 (the two should be a small subscript) - Hydrogen GasH - H (two hydrogens bonded together with a single bond between them), since hydrogen atom/element only has one valence electron to share with the other atom/element.
What type of hydrogens can ionize in a compound?
those bonded to highly electronegative atoms
Why doesn't hydrogen in hydrocarbons make hydrogen bonds?
For hydrogen atoms to have the ability to create hydrogen bonds they must be bonded to an electronegative atom such as fluorine or oxygen. (This creates a partial positive charge on the hydrogen.) Since hydrocarbons are composed of only hydrogen and carbon there is no polarity in the bonds (electronegativity difference of 0.4).
What is positive about NH3 Nitrogen has a strong positive charge hydrogen is negative or they are covalently bonded?
they are covalently bonded
What is the molecular shape of C2H4?
Think of this as H2C3H2 or HC3H3 As carbon is tetravalent and hydrogen is monovalent there must be either two hydrogens bonded to a carbon that is double bonded to another that is double bonded to the third which has the remaining hydrogens double bonded. Otherwise this must be a hydrogen bonded to a carbon that is triple bonded to another carbon which is single bonded to the third carbon which is bound to three hydrogens.
Do all aldehydes have a carbonyl carbon bonded to at least two hydrogens?
All aldehydes except one will have a carbonyl carbon bonded to just one hydrogen. The exception is formaldehyde, the simplest aldehyde, which has a carbon double bonded to oxygen and has two bonds to hydrogen.
How many hydrogen are present in each water molecule?
Water molecules are H2O so there are 2 Hydrogens bonded to 1 oxygen.
Is hydrogen a basic oxide?
Hydrogen is an element. It is not an oxide. A substance becomes oxide when it is bonded with oxygen only. Water is hydrogen oxide which is neutral
The type of chemical bond exists between the atoms in a water molecule?
the two hydrogens and the oxygen are covalently bonded together. water molecules are bonded to other water molecules by hydrogen bonds
What molecule is propene?
Propene is a linear hydrocarbon containing 3 carbons and 6 hydrogens. Two of the carbons are double bonded. Starting at the double-bonded end, you have two hydrogen atoms bonded to the end carbon, then a single carbon double bonded to the first carbon and with a single hydrogen bonded to it, then the third carbon is singly bonded to the second with 3 hydrogen atoms bonded to it.Propene is also known as propylene or methyl ethylene.
In alkanes carbon is bonded to how many other atoms?
Four. A terminal carbon in an alkane is bonded to 3 hydrogens and 1 carbon, while a middle carbon is bonded to 2 hydrogens and 2 carbons.
Which molecule is propyne?
Propyne is a linear hydrocarbon with 3 carbons and 4 hydrogens. Two of the carbons are triple bonded, the remaining carbon is single bonded to the middle carbon Starting at the single bonded end, you have three hydrogens bonded to the first carbon, which is single bonded to the middle carbon. The middle carbon is triple bonded to the last carbon. The last carbon is also bonded to a hydrogen. H ...\ H-C-C≡C-H .../ H
What is 2 hydrogen 1 sulfur and 4 oxygen?
A collection of 7 atoms. There is nothing in the question to indicate that they are bonded into anhydrous sulphuric acid.
Why do scientists use symbols for writing names of elements?
They are easier to write and take less space. It is also a lot less confusing to read something like C3H7NO2 than "three carbons, seven hydrogens, a nitrogen and two oxygens", or to see a structure as CH3CH(COCl)CH2COOH rather than write out "three hydrogens bonded to a carbon, which is bonded to a further carbon along with one hydrogen atom and two further carbons; one of which has one oxygen and one chlorine bonded to it, the other having two hydrogens and a fifth carbon, the last having two oxygens bonded to it, and one of these also bonding to a hydrogen".
