ion
An atom with an electrical charge is called an ion.
This would be called a CATION.
electrical charges flow in a series circuit buy a power source and a load
Thomson believed about atoms, that : An atom consists of a sphere of positive charge with negatively charged electrons embedded in it. Positive and negative charges in an atom are equal in magnitude, thus an atom is electrically neutral and it has no overall + or - charge.
Salt and water both have what we call polar molecules. That means the electrons in the molecule are not divided equally between the atoms of the molecule. This causes partial charge on the molecules atoms. Look up 'why do salt dissolve in water?' if you are confused. I'm just stating an answer. :) Good luck!
A balance of negative and positive charges is called neutrality. This occurs when the total negative charge is equal to the total positive charge, resulting in a system that is electrically neutral.
zwitter ion eg. proteins
An object that has equal numbers of positive and negative charges is called electrically neutral. This means that the overall charge of the object is zero, as the positive and negative charges cancel each other out. Examples include a neutral atom or a neutral molecule.
If it has a positive charge it is a Cation. If it has a negative charge it is an Anion.
Conventional current is defined as the flow of charge from positive to negative. The terms "positive" and "negative" were first applied to charge by Benjamin Franklin; he chose to call the charge left on a rubbed glass rod as "positive". The conventional terminology was well established by the development of batteries and the need to distinguish their terminals. It was more than a century later that the electron was identified as the subatomic particle which carried electric charge. Unfortunately, it turned out to be negative.
Cathode- is the negative electrode.Anode- is the positive electrode.
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.
Because their higher then negative numbers and they are 'POSITIVE'
A negative ion, aka an anion, has a negative charge because it acquired electrons from another now-ion that is positive. An atom because an ion to fill its valence electron shell to the most it can (eight).
We call this Conventional Current Flow, where imaginary positively charged particles are repelled away from a positive charge and attracted towards a negative charge.The reality is that electrons are actually flowing through the conductor. Electrons are negatively charged particles and flow from negative to positive. It's just easier to think of a positive current flowing than a negative current.
You can consider any direction as positive, and the opposite direction as negative. However, in this case it is customary to call a gain "positive", and a loss "negative".
