Do ions have a positive or negative charge?
Ions can have either a positive or negative charge. Positive ions, known as cations, have more protons than electrons, resulting in a net positive charge. Negative ions, known as anions, have more electrons than protons, giving them a net negative charge.
What is the charge on an atom that has five protons nine neutrons and seven electrons?
It would have a negative charge, since the number of electrons - that have approximately the same amount of negative charge as the proton's positive charge in magnitude - is more than the number of protons. Neutrons have no charge (i.e. neutral).
What charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge if it has more negative particles than positive particles. This is because the excess negative particles result in an overall negative charge.
What kind of charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge. Negative particles, such as electrons, carry a negative charge when they outnumber the positive particles, such as protons.
Can an electric charge be positive?
When a process of oxidation takes place the element acquires a unit positive charge. The number of protons are more than the number of electrons in an element which gives the element its positive charge as the protons have a positive charge.
Are negative ions more effective in salting out proteins than positive ones?
No. More negative ions are more effective than less negative ions for salting out. The same is the case with positive ions. Solubility decreases exponentially with increasing magnitude of charge.
If an object has more electrons than protons it has what type of charge?
Since protons have a positive charge and electrons have a negative charge, an atom with more protons than electrons would have a positive charge. Note that an atom with this kind of imbalance is known as an ion.
What is the opposite of a negative charge?
The opposite of a negative charge is a positive charge. Positive charges have more protons than electrons, resulting in an overall positive charge.
Do ions have a positive or negative charge?
Ions can have either a positive or negative charge. Positive ions, known as cations, have more protons than electrons, resulting in a net positive charge. Negative ions, known as anions, have more electrons than protons, giving them a net negative charge.

What charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge if it has more negative particles than positive particles. This is because the excess negative particles result in an overall negative charge.
An object that does not contain equal amounts of positive charge and negative charge has a what?
An object that does not contain equal amounts of positive charge and negative charge is considered to be charged. It may have a net positive charge (if it has more positive charges) or a net negative charge (if it has more negative charges).
How you know if an object has more electrons or protons?
If you put an electric charge of known magnitude near the object, then it will either be attracted to the charge or repelled away from the charge. They will have the same charge if repulsion is observed or different charges if attraction is observed.
What is an atom with a positive charge or negative charge called?
A charged atom is called an ion.If it has more protons then electrons, it has a positive charge.If it has more electrons than protons, it has a negative charge.
Is charge the measure of extra positive or negative particles in an object?
Yes, charge is the measure of extra positive or negative particles in an object. Objects with more electrons than protons have a negative charge, while objects with more protons than electrons have a positive charge. The unit of charge is the coulomb.
What kind of charge does an object have if it has more negative particles than positive particles?
The object would have a negative charge. Negative particles, such as electrons, carry a negative charge when they outnumber the positive particles, such as protons.
Will an atom have a negative charge if it has more protons than nuetrons?
The neutrons do not affect the charge of an atom. The positive charge is on the proton the equal but negative charge is on the electron.If an atom has more electrons than protons it will have an overall negative charge.
