5 What causes an atom to become positively or negatively charged?

Atoms become positively charged when they have a deficit of electrons. Similarly, they become negatively charged when they have a surplus of electrons. Neutral charge, the non-ionized state, is when the number of electrons is the same as the number of protons.

How does salt dissolve in water?
The water molecule is polar. The oxygen and hydrogen atoms do not share the electrons equally. The larger oxygen atom tends to hold the electrons more closely than the hydrogen atoms. This causes the oxygen end of the water molecule to be slightly negatively charged, and the hydrogen atoms to be slightly positively charged. When a salt is added to water, the slightly positive hydrogen atoms attract the negative ions of the salt, and the slightly negative oxygen atom attracts the positive ions of the salt, causing them to dissociate and dissolve in the water.
What causes eggs to become rubbery?
you boil it
How do electron flow in an electric circuit in terms of voltage difference?
Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.
Why does water have a greater degree of surface tension than most other liquids?
Water molecules stick to each other because they can form what are called hydrogen bonds. The positively charged hydrogen atoms are attracted to the negatively charged oxygen atoms of other molecules. This stickiness means that a water molecule wants to be next to as many other water molecules as possible. so if you put something light on the surface of water, it might not be heavy enough to force the water molecules underneath it to separate.
What causes liquid water to become solid ice?
When its somewhere cold that below 30oF degress
An object becomes charged when the atoms in the object gain or lose what?
An object becomes charged when the atoms in the object gain or lose? A) protons B) neutrons C) electrons D)All of the above Answer (1) - Wrong My answer is most definitely D) All Of Above Answer (2) - Right A) and B) because if we assume an object to be neutral at first then if we lose a proton (positively charged) the object becomes negatively charged, if we lose an electron (negatively charged) the object becomes positively charged. Neutrons have no net charge (neutrally charged) so if we take on away nothing happens.
How are Subatomic Particles involved in Lightning?
Electrons are negatively charged subatomic particles. When you have a cloud that at the top of it is most negativity charged and the bottom is positively charged and it rolls over a point in the ground that is negatively charged this causes lightening and actually lightening goes from the ground up to the clouds not from the clouds to the ground as believed - the lightning is composed of a stream of electrons
What causes a positively charged ion?
The loss of electrons.
What causes an atom to have a negative charge?
An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.An atom can be negatively charged if it has an extra electron.
What atomic particle responsible for creating chemical bonds?
There are two, the positively charged protons in the nucleus of atoms and the negatively charged electrons that form a cloud round the nucleus. A chemical bond forms when electron move from one atom to another or become shared between atoms. This movement of electrons causes an electrical charge imbalance (one atom becomes positively charged and the other negatively charged) and the two atoms become bonded one to the other to balance out the charge difference.
What is the definition of a battery?
potato battery do not directly produce electricity. The chemical composition of the potato when combined with zinc in metals together with copper is what causes a reaction between the released positively charged and negatively charged ions of the potato resulting in the flow of electricity.
Why do halogens form ionic compounds with metals?
Halogens have a high electronegativity and metals have a low electronegativity in general. Therefore, metals tend to give up their valence electrons to the halogens. This causes the halogens to form negatively charged ions and the metals to become positively charged ions. The electrostatic attraction between the oppositely charged ions forms the ionic bond which forms the ionic compound.
What causes an atom to be positively charged?
It loses one or more of its electrons.
How does the parts of a cell interact to produce a current?
In a electrochemical cell or a battery there are two electrodes and an electrolyte. Chemical reaction occurs between the electrodes and the electrolyte which causes one of the electrodes to be positively charged and the next one to be negatively charged. The differences between the two electrodes creates voltage. When the battery is now connected to a circuit it makes a current.
Why do some charged objects pull each other while other charged objects push each other?
The charged object may induce a separation of charges in the neutral object.The charged object may induce a separation of charges in the neutral object.The charged object may induce a separation of charges in the neutral object.The charged object may induce a separation of charges in the neutral object.
What causes plasma to form?
Plasma forms when a gas becomes extremely hot. When this happens, the gas' atoms gain lots of energy. This energy causes the electrons to detach from the nuclei of the gas' atoms. When the negatively charged electrons detach, the positively charged protons and neutral particles called neutrons in the nuclei are left.
What causes an atoms to become positively or negatively charged?
The ratio of electrons (negative) to protons (positive.). An atom is nutruel in normal condition. It has positive proton and negative electron in a balanced form.when electrons emit from atoms than a positive charge form in atom. And vice versa.
