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

What is the most electrically conductive metal?
Silver is the most electrically conductive metal.
Is the cis or trans community more polarized in terms of societal acceptance and representation?
The trans community is generally more polarized in terms of societal acceptance and representation compared to the cis community.
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.
What type of light source is typically used in a polarimeter to measure the rotation of polarized light?
A polarimeter typically uses a monochromatic light source, such as a sodium lamp or a laser, to measure the rotation of polarized light.
What does 2Na mean?
2Na represents two atoms of sodium. The prefix '2' indicates that there are two sodium atoms.
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 object is not an electrically neutral?
A object without electrical charges.
What object is not electrically neutral?
A object without electrical charges.
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.
When positive and negative charges are sparated into different parts of an object the object is said to be?
polarized
