Positively charged objects have more protons than electrons. Negatively charged objects have more electrons than protons.
Yes. The acceleration depends on the aerodynamics of the shapes of the objects - not their mass.
When volume is constant, the masses of two objects are in direct proportion to their densities.
Because of it's ability to seperate positive charge from negative charge. The potential energy may have been produce by the device as in a battery or solar cell, or it may have been "injected" into it as in a capacitor but irreguardless, the better the device's ability to keep the negatively charged electrons seperated from the positively charged spaces, The more potential energy it can hold.So the answer would simply be seperation of charge.
No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.
They differ in the number of protons in their nucleus.
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
Sodium has 11 positively charged protons. (All atoms have positively charged protons, though they differ in hte number of protons).
Neutrons are neutral sub atomic particles found in the nucleus of an atom (along with positively charged protons). Electrons are negatively charged sub atomic particles that are revolving around the nucleus of an atom. The mass of neutron is 1 amu and the mass of electron is about 1837 times less than that of neutron.
Alpha rays are positively charged, beta negatively charged and gamma rays is an electromagnetic wave(like light) which has no charge. They have obtained their charges on basis of where they originated from within the atom.
Differ from what precisely? If you are talking about from the other substances it differs by an excess or shortage of electrons. If you are talking about magnetic substances then these charged objects are charged and yes they also would possess magnetic field if they were in motion. Magnets on the other hand gain their magnetism from the internal alignment of electrons.
Negatively charged and contains less sodium
did the sound produced by the objects differ
The plum pudding model displays the atom as negatively charged electron embedded in a fluid of positive charge, thus the name plum for the electron and the pudding for the positive fluid thought to balance the negative charges. The Rutherford model is based on the gold foil experiment and it has a nucleus in which is extremely small, positively charged and dense. The model has lots of empty space around the nucleus which was where the electrons were placed.
I assume you mean 'anion' instead of 'onion'.A cation is a positively charged ion. It loses one or more negatively charged electrons when forming ionic compounds. An anion is a negatively charged ion. It gains one or more electrons when forming ionic compounds. Every ionic compound must contain both a cation and an anion so that the compound as a whole has no charge.A common example: In the ionic compound table salt (NaCl), sodium (Na+) is the cation, and chloride (Cl-) is the anion.It may also be helpful to note that cations are almost always metals and anions are typically nonmetals.On a lighter note:If you really did mean 'onion', then the answer is simple: one goes in your salad and one does not. :)
Na (sodium) is an atom in singularity, whereas NaCl (sodium chloride) is a compound made up of the two atoms Na (sodium) and Cl (chlorine). They are combined due to the attraction between positively charged and negatively charged atoms. Na is positively charged with one more proton than electrons (1+) and Cl is negatively charged with one more electron than protons (1-). I hope that helped :-)

Protons and neutrons are found in the atom's nucleus and represent practically all of an atom's mass. Protons are positively charged, while neutrons are neutral. Electrons orbit the nucleus in regions called energy levels (or shells) and carry a negative charge.
