Because, unless bonded to another hydrogen atom, the "covalent" bond is actually partially ionic, meaning the electron shared in the bond tends to spend more time close to the other atom making the hydrogen partially positive. This is due to electronegativity. Most other atoms are more electronegative than hydrogen, meaning they have a stronger attractive force for electrons than hydrogen does, so the other atom pulls on the hydrogen more strongly and ends up being more negative in the bonding pair than hydrogen.
In covalent bonds, not all electrons are shared equally. Oxygen is more electronegative than Hydrogen, so it attracts the electrons closer to the Oxygen than the Hydrogen.
The chlorine will have a partial negative charge.
That atom has a greater attraction for electrons.
because hcl is a polar covalent compound therefore it results in a fractional negative and positive on them .thus it ionize in water.
The hydrogen bond involves hydrogen in a covalent bond with a highly electronegative element, like oxygen in water. Pure hydrogen H2 involves 2 atoms with exactly the same electronegativity. In water the large difference in electronegativity means that the bond is polar covalent. In addition to that, the hydrogen is not quite, but nearly a point nucleus because there are no other electrons in hydrogen than those shared. This causes a very strong attraction --- not a real bond -- between the hydrogen and the highly negative oxygen in an adjacent molecule. This is the real hydrogen bond, the attraction of the hydrogen for an element in another molecule. Real bonds are within one molecule.
Because the positive hydrogen atoms of the water molecule attach with and dissolve the negative atoms of other molecules, and the negative oxygen atom attaches and dissolves the positive atoms of other molecules.
3-methyl amine, aka methyl amine, conatins N-H bonds (polar covalent bonds). Ethane contains only C-H bonds (non-polar covalent bonds). Since the N-H bonds are polar and Nitrogen being more electronegative (ability to attract electrons), it has a slighly negative charge by pulling the elecrons from the hydrogen it is bonded to, giving the Hydrogen a slighly positive charge. The positive H's of one molecule will be attracted to the negative N's of another molecule. This is the force that 'holds' the molecules close to each other. This is why it takes more kinetic energy (temperature) to convert it to a gas than ethane, which essentially has no charge and subsequently very little attraction to other ethane molecules.
Hydrogen bonding. Water molecules electrons are not sharred evenly between the hydrogen and oxygen atoms. The easiest way to explain it is that the oxygen atom "hogs" the electrons. Since it has 8 protons in it's nucleus the oxygen has a greater pull. Hence the oxygen is slightly negative (negative charge of electrons) and ther hydrogen side has a slightly positive charge. Hydrogen bonding is part of the category known as Van Der Wall forces. Basically, the hydrogen part of the water molecule bonds with a slightly negative part of another molecule. This allows for adhesive and cohesive bonding cababilities of water.
Positive plus positive equals positive. Negative plus negative equals negative. Positive greater than negative equals positive. Negative greater than positive equals negative.
Negative.
prompt:how did the railroads impact society, was it a positive impact or negative ?explain
+*-=-. Example. 3*-3=-9.
Negative, because 5 is an odd number
because of the electronegativity
That simply means that there is both a positive and a negative number which, when squared, gives you 64.
LOVE to HATE = Hate (Negative)LOVE to LOVE = Love (Positive)HATE to HATE = Hate (Negative)HATE to LOVE = Hate (Negative)HATE is a NEGATIVE numberLOVE is a POSITIVE number
Negative times negative equals positive. Positive times positive equals positive. Positive times negative equals negative. If you have more than two numbers, multiply the first two and then apply these rules to each successive number in turn.
because hcl is a polar covalent compound therefore it results in a fractional negative and positive on them .thus it ionize in water.
Each hydrogen atom has 1 electron. When two hydrogen atoms combine they each share that electron with the other hydrogen atom, creating a covalent bond and a molecule of H2.
No, any 2 negative numbers multiplied together equal a positive number
