When a molecule becomes more negative, it means that it has gained additional electrons, resulting in an increase in its overall negative charge. This can occur through processes such as electron transfer or the formation of chemical bonds with more electronegative atoms, causing the molecule to exhibit a greater overall negative charge distribution.

Why are ions made?
Ions are made for clothes can not be wrinkly An ion is formed when an atom [or molecule] gains or loses one or more electrons. If an atom or molecule gains an electron it acquires negative charge. If the atom or molecule loses an electron it becomes positively charged.
Will this entropy change by positive or negative?
If the system becomes more disordered, the entropy change will be positive. If the system becomes more ordered, the entropy change will be negative.
In the molecule FBr which atom is the negative pole?
In the molecule FBr, the negative pole is the fluorine atom because it is more electronegative than bromine. This causes the electrons in the bond to be pulled closer to the fluorine atom, giving it a partial negative charge.
If an atom loses an electron 'negative charge' it becomes?
If it loses an electron (negative charge) it becomes positive.
Why when ions gain it becomes negative and when ion loses it becomes positive?
Electrons are negatively charged. When an atom gains an electron it gains this negative charge, and so it becomes negative. When it loses it again it has lost that negative charge and becomes more positive.
Why is molecule polar?
If you mean "Why is a molecule polarized" it would be because there is a more negative charge to one end of the molecule than the other.
When the proton number and electron number are unequal the atom or molecule what?
When the proton number and electron number are unequal, the atom or molecule becomes an ion. If there are more protons than electrons, it becomes a positively charged cation. If there are more electrons than protons, it becomes a negatively charged anion.
Why is a polar molecule?
A molecule is polar because it has an uneven distribution of electrons within it. For example the oxygen in H2O has a higher electronegativity than the hydrogen. This means that the oxygen will possess more of the electron, and therefore more of the negative charge than the hydrogen, leading to a polar molecule.

What does a negative Hf for molecule mean?
Energy was released when the molecule was formed from its elements
What is the term for the overall direction of partial negative charge in a molecule having one or more dipoles?
The term for the overall direction of partial negative charge in a molecule with one or more dipoles is "dipole moment." It is a measure of the separation of positive and negative charges within a molecule and indicates the polarity of the molecule.
The water molecule H2O is polar because it contains two polar single bonds and?
It's polar because the oxygen molecule is more electronegative than both the hydrogen atoms together. This means that the oxygen atom attracts the electron of each hydrogen more strongly than the hydrogens, so the electrons spend more time around the oxygen. Since a hydrogen by itself is neutral, when its electron (negative) is pulled away it becomes (partially) positive. And the oxygen, having more of the electron, becomes more negative. So you now have a molecule with an area of negative charge (the oxygen) and an area of positive charge (the hydrogens). This positive/negative charge within the molecule makes it polar.
A molecule that gives up an electron becomes what?
Oxidized.Oxidation involves a loss of electrons.The answer above in a general context is wrong I'm afraid - If an atom loses an electron it becomes an ion and the same if it gains one - and electrically charged particle.
If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
In the molecule FBr which atom is the negative pole?
In the molecule FBr, the negative pole is the fluorine atom because it is more electronegative than bromine. This causes the electrons in the bond to be pulled closer to the fluorine atom, giving it a partial negative charge.
What does the term "ion" mean in chemistry?
In chemistry, an ion is an atom or molecule that has gained or lost one or more electrons, resulting in a positive or negative charge.
