How is it possible for an atom to have no charge even though it is made up of protons neutrons and electrons?
An atom can have no charge when the number of protons (positively charged) is equal to the number of electrons (negatively charged), resulting in a balanced charge overall. This balance of positive and negative charges within the atom leads to a net neutral charge.
Why an atom has no charge even though it contains charged particle?
There are particles within the atom that are charged. Protons have a positive charge, while neutrons have a neutral charge(in other words they have no electrical charge). If you take a look at the website below, the blue circles in the centre represent neutrons, with no charge, and the red circles are protons, with a positive electrical charge. The gray spheres orbiting around the nucleus(centre of the atom with most of the mass) represent electrons, which have a negative charge and weigh about 1/2000 of the mass of a proton/neutron. visitthis site http://upload.wikimedia.org/wikipedia/commons/thumb/e/e1/Stylised_Lithium_Atom.svg/180px-Stylised_Lithium_Atom.svg.png
What is true electric currents?
True electric currents refer to the movement of electric charge carriers through a conductor, such as electrons in a wire. It is this flow of charge that powers electrical devices and circuits. The direction of the current is defined as the flow of positive charge, even though in reality it is often negative charges (electrons) that are moving.
How is static electricity built up?
everything we see is made up of tiny little parts called atoms. The atoms are made of even smaller parts. These are called protons, electrons and neutrons. They are very different from each other in many ways. One way they are different is their "charge." Protons have a positive (+) charge. Electrons have a negative (-) charge. Neutrons have no charge.Usually, atoms have the same number of electrons and protons. Then the atom has no charge, it is "neutral." But if you rub things together, electrons can move from one atom to another. Some atoms get extra electrons. They have a negative charge. Other atoms lose electrons. They have a positive charge. When charges are separated like this, it is called static electricity. If two things have different charges, they attract, or pull towards each other. If two things have the same charge, they repel, or push away from each other. So, why does your hair stand up after you take your hat off? When you pull your hat off, it rubs against your hair. Electrons move from your hair to the hat. Now each of the hairs has the same positive charge. Things with the same charge repel each other. So the hairs try to move away from each other. The farthest they can get is to stand up and away from all the other hairs. If you walk across a carpet, electrons move from the rug to you. Now you have extra electrons. Touch a door knob and ZAP! The electrons move from you to the knob. You get a shock.
How can a negatively charged rod charge an electroscope positively?
When a negatively charged rod approaches an electroscope, it induces a separation of charges within the electroscope. Electrons in the electroscope are repelled by the negative charge of the rod and move to the opposite end of the electroscope, leaving a net positive charge at the top. This gives the electroscope a positive charge, even though the initial influence was negative.
Do cations always have a positive charge?
No, cations do not always have a positive charge. Cations are ions that have a positive charge because they have lost electrons. However, some cations can have a neutral or even a negative charge depending on the number of electrons they have lost.
What type of electrical charge is associated with a single atom?
If an atom has an even number of protons and electrons, it has no charge, so it is neutral. If it has an uneven number of protons or electrons and has a positive or negative charge depending on which has more. It is then called radioactive.
If an atom has 15 protons 13 neutrons and 18 electrons what is the atom's electrical charge?
the nucleus always has a positive charge. The atom on the other hand in its singular state will have no charge as the electrons negative charge counter the protons positive charge. in this example there will be 31 electrons The element would be Gallium but there are not enough neutrons in your question to even make a viable isotope. Gallium typically has 31 protons and 39 neutrons
How is it possible for an atom to have no charge even though it is made up of protons neutrons and electrons?
An atom can have no charge when the number of protons (positively charged) is equal to the number of electrons (negatively charged), resulting in a balanced charge overall. This balance of positive and negative charges within the atom leads to a net neutral charge.
How is it possible for an object to be neutral if it contains millions of electrons?
Although a substance may contain millions of negatively charged electrons, it also contains millions of positively charged protons. The object will be neutral when the number of protons equals the number of electrons.
Why an atom has no charge even though it contains charged particle?
There are particles within the atom that are charged. Protons have a positive charge, while neutrons have a neutral charge(in other words they have no electrical charge). If you take a look at the website below, the blue circles in the centre represent neutrons, with no charge, and the red circles are protons, with a positive electrical charge.

1 coulumb charge is equal to how many electrons?
The elementary charge ... the amount on one electron or one proton ... is 1.602 x 10-19 coulomb.So, in order to collect one coulomb, you'd need 6.242 x 1018 electrons or protons.(That's the number of electrons that pass by the middle of the wire every secondwhen the current in it is 1 Ampere.)
Why do the atom's charge equal zero?
Because there is an even amount of protons and electrons
What can be determined if you know the atomic number of an electrically neutral atom?
The number of electrons can be determined if the overall charge and number of protons are known. If the charge of an atom is neutral, then how ever many protons it has it will also have that number of electrons.
How do atoms remain neutral?
Atoms are neutral as long as they contain the same number of protons as electrons. If there are more electrons than protons, the atom has a negative charge. If there are less electrons than protons, the atom has a positive charge.
What kind of charge does an electron have when it gains or loses electrons?
Remember- Pro means + Therefore, a proton has a + charge, an electron has a - charge, and neutrons (neutral) have no charge. Normally an atom has an even number of protons and electrons, and can have any number of neutrons and still be the same element. When you add electrons, you end up with a slight negative charge because there are more negatively charged particles than positive ones. When you remove electrons, you get a slight positive charge, because there are now more positive particles than negative ones. This usually occurs as a result of polar covalent bonds. A atom with a slight charge in either direction is called an ion. A negative ion is a anion, while a positive ion is a cation.
Why do atom have no electric charge even though most of their particles have charge?
Non ionic atoms have no electric charge, even though most of their particles have charge, because the positive particles (protons) balance the negative particles (electrons).
