They do not always. The sum of two negative numbers is negative.
Because two negative multiplied together equal a positive. So after the first multiplication we have a positive and a negative. When we multiply these we have a negative.
Yes. In multiplication, the product is positive if the factors have the same sign,and the product is negative if they have oppositesigns.
A negative times a negative always equals a positive, no matter what the numbers are.
If two numbers have the same sign, their product is positive. If two numbers have opposite signs, their product is negative. So the answer is 'yes'.
equal numbers of positive and negative charges.
When the total positive charges are equal to the total negative charges in an atom or a molecule, the overall charge is neutral. This means that the number of protons (positive charges) is equal to the number of electrons (negative charges), resulting in a balanced electrical charge.
The net charge of an object with equal amounts of positive and negative charges is zero. Positive and negative charges cancel each other out, resulting in no overall charge on the object.
No , an atom always has equal numbers of protons and electrons. If it has more charges of one kind than another is called an ion. Obviously this is caused by the number of protons and electrons compared to each other. If it has more positive charges, it has more protons than electrons, making it a positive ion. If it is a negative charge, it has more electrons than protons, it is a negative ion.
No
no it doesnt. two negative numbers equal a negative number. two postivie numbers equal a positive number. one negative and one positive number equal a negative number.
Atoms have equal numbers of protons and electrons, which carry opposite charges: protons are positive and electrons are negative. The equal number of positive and negative charges cancel each other out, resulting in an atom that is overall neutral.
Electrons have negative electric charges equal in magnitude to the positive charges of protons.
Positive and negative charges.
positive
A balance of negative and positive charges is called neutrality. This occurs when the total negative charge is equal to the total positive charge, resulting in a system that is electrically neutral.
An object is electrically neutral when it has an equal number of positive and negative charges, resulting in a balance of overall charge. This balance occurs when the number of protons (positive charges) is equal to the number of electrons (negative charges) in the object.
