If you want to look at it simply, an electron is -1 charge and a proton is +1 charge. If you want to use coulombs as the unit, one elementary charge is 1.60x10^-19. so an electron would be -1.60x-19C while a proton is +1.60x-19C.

What does it mean for an atom to be neutral?
It means that the atom has no charge (not positive or negative). This is because there are an equal number of protons and electrons in the atom. When an atom has a charge it is called an ion.
What are the Three basic subatomic particles?
The three sub-atomic particles are:# Proton # Electron # NeutronAtoms are made up of Electrons, Neutrons, and Protons. These subatomic particles are known to be made up of even smaller particles. Particle accelerators are being used today to discover more of these particles.
What number is used to determine how many electrons are in a neutral atom?
The atomic number (the number of protons in the atom). Neutral charge = 0 = (number of protons - number of neutrons). Therefore, number of protons = number of neutrons
How is the concept of effective nuclear charge used to simplify the numerous electron- electron repulsions in a many electron atom?
a) How is the concept of effective nuclear charge used to simplify the numerous electron-electron repulsions in a many-electron atom?Effective Nuclear Charge- the (net) positive charge experienced by an electron in a many electron atom. This charge is not the full nuclear charge. It accounts for the shielding of the nucleus by other electrons in the atom.The nucleus is surrounded by electrons. These electrons are shielded from the nucleus by electron repulsions. The effective nuclear charge is less than the actual nuclear charge because the repulsions of the electrons needs to be taken into account.This is done in the equationZeff = Z (protons) - S (screening constant, the inner core amount of electrons)b) Which experiences a greater effective nuclear charge in a Be atom, the 1s electrons or the 2s electrons?The 1s electrons would have a greater nuclear charge. The number of electrons between the 1s electrons and the nucleus is less than the number of electrons between the 2s electrons and the nucleus. This means the screening constant is larger. When you subtract the larger amount of electrons from the amount of protons, 4, the difference will be less, meaning the value of the effective nuclear charge will be less.
How many electrons must be used in the Lewis structure of the hydroxide ion OH-1?
Oxygen contains 6 Protons, Hydrogen contains 1 Proton, and the total charge is -1. Therefor, the number of Electrons is 8.
Why are only protons and neutrons used to calculate atomic mass?
Electrons do not contribute to the weight. They are only used to neutralize the charge

An atom that has equal number of protons and electrons is called what gas is used in exchange?
NeutralNeutral, or in other words has no charge.

What does it mean if atom has a neutral charge?
The term 'neutral charge' is meaningless, if an atom is neutral then it has no charge if it has charge then it can not be neutral. 'Neutral' means that it will not be deflected in an elecromagnetic field. Particles inside atoms are either electrically neutral (neutrons) or are 'charged' (protons and electrons). being charged means that they would be affected by an electrical field. If an electrical field is applied to either protons and electrons, they are deflected in opposite directions. Therefore protons and electrons have opposite charges. The convention is that protons have a '+' charge, and the electrons a '-' charge, although any suitable description (up/down, black/white, left/ght etc) could be used as long as one description was the opposite of the other. All atoms are neutral, as they have the same number of + protons as - electrons in them. If an atom loses or gains one or more electrons it becomes iteslf charged and is then known as an 'ion'.
What number is used to determine how many electrons are in a neutral atom?
The atomic number (the number of protons in the atom). Neutral charge = 0 = (number of protons - number of neutrons). Therefore, number of protons = number of neutrons
Why plus and minus symbols are used to specify the electron charges?
Because protons have a positive charge, hence the plus sign, and electrons have a negative charge, hence the minus sign.
What molecule collects the majority of the electrons from the food that you eat?
Molecules that have a positive charge collect electrons. This because they have more protons than electrons and positive charge attract negative charged electrons.
Atomic mass represents the weight of an atoms protonsneutronsand electrons however the atomic mass is generally used to refer to just the number of protons and neytrons why?
Each electron weighs only about 0.0005 atomic mass unit, but protons and neutrons weigh 1 atomic mass unit each. Since there are the same number of protons, and usually even more neutrons, in an atom as there are protons, the weight of the electrons can be neglected in most chemical calculations.

What unit is used to measure the electric force that causes the electrons to move?
This question is incorrect. Electricity is defined as the accumulation/ movement of electrons. The reason that electrons move is the same reason gravity exisits. They are just natural phenomena. There is no electric force that makes electrons move. It is the attractive/ repulsive forces between the protons and electrons. There is no such defined force you are asking about. The closest unit to answer this question is the Coloumb.
