because if they weren't, they would rapidly attract opposite charges and become neutral.
because it is made of something
Vibration makes energy, friction is heat, and heat is energy. So when a particle is electrically charged it makes energy.
gravity is what makes objects fall
The simple answer is that gravity is actually an extremely weak force. A common fridge magnet can overcome the attraction of the entire Earth! Gravity only becomes powerful for very heavy objects like planets and stars. Everyday objects as well as people are simply not massive enough to provide much of a force. The reason why gravity (though weak) is the dominant force at long range is that gravity only adds to itself; adding more mass only makes it stronger and you cannot really stop gravity. Compare this to the electromagnetic force; although it is much more powerful it acts on charges, and both positive and negative charges exist. Therefore you can stop the electromagnetic force by negating a charge by adding the opposite charge to it. The Universe is largely electrically neutral, so long range electromagnetic forces do not appear.

When they have both equel negatives and positives
He makes them special and bewildering.
Most of the time yes, electron gain = makes it negative, electron loss = makes the atom positive -------------------------------------------------------------------------------------------------------- In any atom, the no. of electrons and protons are equal. This is the reason which makes an atom electrically neutral. If electrons are added, then an anion is formed which is negatively charged. If electrons are lost, then a cation is formed which is positively charged.
The question makes no sense. Objects are buoyant in a surrounding fluid; change the fluid, change their buoyancy.
a green crayon cause when you color with it it makes it green and cytoplasm makes the stem green.
Atoms are built form 3 types of particles Electrons (which are electrically negative) Neutrons (which are electrically neutral) Protons (which are electrically positive) Nature likes things to be balanced so when atoms are put together, nature makes sure that the number of Electron the atom has is matched by the number of Protons. This makes all atoms electrically neutral. However, when atoms react with each other chemically, they can share or swap electrons with each other which means that they are no longer electrically neutral (in this state they are called "ions"). Nature therefore requires that the stuff they have made (called a compound) when joining together is, overall electrically neutral and bonds them together so that this is achieved. This is why chemical compounds exist and are stable.
Vibration makes energy, friction is heat, and heat is energy. So when a particle is electrically charged it makes energy.
It glows when electrically stimulated.
Mainly because that's the definition of a "neutral" atom ... one having zero net charge.
When elements first come together they are both electrically neutral. When they get close enough, an electron transfers from the sodium to the chlorine. This makes the a positive sodium ion, Na+, and a negative chlorine ion, Cl-.
The short answer is no, not unless it bothers you. It is, however, something to discuss with your health provider (mental or general) next time you see them. Unless it bothers you or upsets you or your quality of life, you should be okay.
because all acid has some kind of reaction with magnesium.
