A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.

An atom contains fewer electrons than protons has as negative ionic charge?

Electrons have a negative charge, and protons have a positive charge. If i have more protons(plus charges) than electrons(minus charges) overall the atom will have a positive charge(mabye +1 or +2 etc....depending how many more protons there are compared to electrons) If there are more electrons(minus charges) than protons(plus charges) then overall the atom will have a negative charge(mabye -1 or -2 etc....depending how many more electrons there are compared to protons) These charged atoms are known as ions.


What charge are protons neutrons and electrons if they are part of carbon?

Protons are always postive, neutrons are always neutral and electrons are always negative. Carbon has no charge because it has as many protons as it has electrons.


What is the charge of an ion that contains 16 protons?

i think it depends how many electrons it has. then you do something like subtract the electrons from the protons. electrons are negative, protons are positive.


If Ca has a 2 negative charge how many protons does it have?

It has 20 protons, irrespective of its charge.


How many electrons do protons have?

There are the same number of protons as electrons in each atom unless the atom does not have a neutral charge, if it has a negative charge it has that more electrons, and if it has a positive charge it has that much more protons hope this helps


How many electons are in a neutral atom?

A neutral atom has as many electrons as protons. This is because protons have a positive charge and electrons have a negative charge, but because there are the same number of them, they cancel each other out.


If Chlorine has 17 protons and negative one charge how many electrons does it have?

Chlorine with 17 protons and a -1 charge has 18 electrons. This is because the number of electrons should equal the number of protons (in this case, 17) plus or minus the charge (in this case, -1).


If an atom of an element has six protons and eight neutrons how many electrons is in this atom if its neutral?

When we consider charged particles, we are only concerned with protons and electrons. Neutrons have no charge, so they don't contribute to a positive or negative charge. Protons have a positive charge and electrons have a negative charge. They are both equally positive and negative, that is to say one proton cancels out the charge of one electron. So as long as there are equal numbers of protons and electrons, the particle will be neutral. If there are six protons, then there needs to be six electrons in order to be neutral.


Why are there as many electrons as protons in a atom?

Because Electrons have a negative charge (e-) and Protons have a positive charge (p+), so to create a balanced atom you must have the same number of e- as p+


Why are electrons negative?

Electrons are negative because they have a fundamental property called charge, which is a fundamental property of matter. Electrons have a negative charge, while protons have a positive charge. This charge difference is what allows electrons to interact with other particles and create the electrical forces that govern many aspects of the physical world.


How many electrons orbit the nucleus if the atom has no charge?

If the atom has no charge, it is neutral, meaning the number of electrons orbiting the nucleus is equal to the number of protons in the nucleus. This is because protons carry positive charge and electrons carry negative charge, balancing each other out in a neutral atom.


If an atom has 80 protons and 121 neutrons and is not in an excited state how many electrons does the atom have?

The number of electrons in a neutral atom is equal to the number of protons, which is 80 in this case. This is because in a neutral atom, the positive charge of the protons is balanced by the negative charge of the electrons.
