An atom has a charge of -3 in its orbitals. which statement must be true in order for this atom to have no net charge? there are three positively charged protons outside the nucleus. there are three neutral neutrons in the nucleus. there are three positively charged protons in the nucleus. there are two positively charged protons in the nucleus and one in an orbital.

For this atom to have no net charge there must be three protons in the nucleus.

The electrons in the orbitals carry the negative charge, so there must be three electrons.

The atom is neutral, so there must be three positive charges.

The protons carry the positive charge and are in the nucleus, so there must be three protons.

There are three positively charged protons in the nucleus.

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an atom in an electrically neutral atom.

Atomic number = Number of electrons = Number of protons

Ions are formed when an atom looses or gain electrons.

When an atom looses its electron, it results in the formation of a positive ion which is known as cation and when an atom gains electron, it results in the formation of a negative ion known as anion.

Thus if an atom has a charge of -3 , it means the atom has gained three electrons and thus for the atom to be electrically neutral, it must contain three protons which are positively charged and present in the nucleus.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
