Before an impulse is received, a resting neuron is polarized with different charges on either side of the cell membrane. The exterior of the cell is positively charged with a larger number ofsodium ions present compared to the interior of the cell. The interior of the cell is negatively charged since it contains more potassium ions than the exterior of the cell. As a result of the differences in charges, an electro-chemical difference of about -70 millivolts occurs.IT means that electrical charges on the outside of the membrane is positive while inside is negative
When an object is electrically polarized, its positive and negative charges become separated, leading to the creation of an electric dipole moment. This results in one side of the object being more positively charged while the other side is more negatively charged.
Electrically polarised objects have had their chrages seperated, so one side will be positive, and the other side will be negative. This usually happens when an insulated object is brought close to (but doesn't touch) a charged object. Electrically charged objects will have lost or gained charge, so the whole thing will either be positive or negative. If you run a comb through dry hair a few times, it will become electrically charged. You can then use the comb to pick up some tiny pieces of paper, because the bits of paper become electrically polarised.
When a negatively charged object comes near neutral object and the charges in the neutral object split on two different sides of the surface with the positive charge closer to the negatively charged object.
"Polarized" means that the object has a separation of positive and negative charges - one side is more positive, the other is more negative. The total charge might be zero (electrically neutral) in this case.
The job of the cell nucleus is to control all of the functions in a cell, and in some cells it also holds the DNA.

Is the magnesium atom electrically neutral or electrically charged?
The magnesium atom is electrically neutral. It has 12 protons in the nucleus, which are positively charged, and 12 electrons surrounding the nucleus, which are negatively charged. The positive and negative charges balance each other out, resulting in an overall neutral charge for the atom.
Are tantalum capacitors polarized?
Yes, tantalum capacitors are polarized, which means they have a specific positive and negative terminal. Applying voltage in the wrong polarity can damage the capacitor. It is important to observe the correct orientation when installing tantalum capacitors to avoid failures.
Which atom H or O is negatively polarized (electron-rich)?
Oxygen (O) is negatively polarized, as it has a higher electronegativity compared to hydrogen (H). This means that oxygen attracts electrons more strongly, making it electron-rich.
What does 2Na mean?
2Na represents two atoms of sodium. The prefix '2' indicates that there are two sodium atoms.
The highly polarized nature of compounds containing carboxyl groups are attributed to the presence of two what?
The highly polarized nature of compounds containing carboxyl groups is attributed to the presence of two functional groups: the carbonyl group and the hydroxyl group. The electronegative oxygen atoms in these functional groups draw electron density away from the carbon atom, resulting in a highly polarized molecule.
How does an electrically polarized object different from an electrically charged object?
It will still have a electrical charge.
What does it mean to say a object is electrically polarized?
When an object is electrically polarized, it means that the charges within the object have been rearranged in such a way that one side of the object becomes more positively charged while the other side becomes more negatively charged. This creates an electric dipole moment within the object.
What is normally the net charge of an electrically polarized object?
An electrically polarized object typically does not have a net charge. It has an overall neutral charge, but the charges within the object are separated, creating regions of positive and negative charge, leading to an electric dipole moment.
Which type of objects can be electrically polarized?
Mostly dielectric materials can be electrically polarized, including ceramics, polymers, and some liquids. Metals and conductors do not get polarized because their electrons are free to move around.
What type of objects can be electrically polarized?
Molecules with a permanent dipole moment, such as water molecules or some organic compounds, can be electrically polarized. Additionally, certain types of crystals and materials with asymmetric charge distributions can also be polarized when an electric field is applied.
What is the difference between electrically charged and a neutral object?
An electrically charged object has an imbalance of positive or negative charges, while a neutral object has an equal number of positive and negative charges. Charged objects can attract or repel other charged objects due to their electric fields, whereas neutral objects do not exert such forces.
what objects can be electrically polarized?
Objects that have asymmetrical distribution of charge, such as molecules with a permanent dipole moment or materials with aligned dipoles, can be electrically polarized. Examples include water molecules, certain crystals like quartz, and some ceramic materials.
When the total charge on an object is zero the object is electrically what?
When the total charge on an object is zero, the object is electrically neutral. This means it has an equal number of positive and negative charges, resulting in no overall charge.
What happens when an object becomes polarized?
When an object becomes polarized, its molecules align in a way that creates positive and negative ends, leading to the separation of charges. This results in the object having a net dipole moment, making it capable of interacting with electric fields and other polarized objects. Magnetic materials can also become polarized, aligning their magnetic domains in a specific direction.
What object is not electrically neutral?
A object without electrical charges.
What object is not an electrically neutral?
A object without electrical charges.
When positive and negative charges are sparated into different parts of an object the object is said to be?
polarized
