Polar molecules have partial negative and partial positive charges on opposing sides. They have a net dipole as a result of the opposing charges.
The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).
In an electrical circuit, electicity moves from the positive (+) end of the power source to the negative (-) end.
The Banded end of diode represents Cathode.If you want the diode to be forward biased then the Cathode is made more negative than Anode.For reverse biasing of Diode (Zener Diode) The Cathode is kept positive.However the mail carrier of current in the Cathode is Electrons which are negative.
Positive : makes life easier negative : makes us lazy
as direction of current reverses it is shown in form of positive and negative cycles
Polaric molecule
H2o
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
Polaric molecule
A polar molecule is one that has a negative and positive end due to an uneven distribution of electron density. Water is a common example of a polar molecule, with its oxygen atom being partially negative and its hydrogen atoms being partially positive.
A polar molecule such as water
A zwitterion has a formal positive charge at one end of the molecule and a negative one at the other end.
yes. the positive end of the molecule attracts the negative end of the adjacent molecule
A zwitterion has a formal positive charge at one end of the molecule and a negative one at the other end.
Molecules that have partially positive and negative regions are called polar molecules. Polarity results from an unequal attraction of electrons between the atoms that make up a molecule. The electrons are more drawn towards atoms with a higher electronegativity, thus making these atoms partially negative.
yes. the positive end of the molecule attracts the negative end of the adjacent molecule
Polarity refers to the positive or negative charge of a molecule or its parts. In chemistry, it describes the separation of charge in a molecule that has areas of differing electronegativity. A polar molecule has a positive end and a negative end.
