When is an atom neutral When mass number equals number of protons equals number of electrons or when atomic number equals number of protons equals number of electrons?
An atom is neutral when the number of protons in the nucleus equals the number of electrons surrounding the nucleus. This means that the atom has no overall charge, as the positive charge of the protons is balanced by the negative charge of the electrons. The mass number, which is the sum of protons and neutrons, does not necessarily impact the neutrality of the atom.
What do the charge of electrons equal in a neutral atom?
The negative charge of the electrons equals the positive charge of the protons in a neutral atom. In other words, the numbers of electrons and protons are equal.
How many protons and electrons are in present in a potassium atom?
A potassium atom has 19 protons and 19 electrons. The number of protons always equals the number of electrons in an atom, as they balance each other to maintain the atom's overall charge neutral.
Why is the the overall charge of the atom neutral?
Because in a neutral atom, there are an equal number of positive protons and negative electrons. The equal number causes the charges to cancel out, making the net charge 0.An atom is made of positive protons and neutral neutrons in the nucleus, and negative electrons surrounding the nucleus. An normal atom has the same number of protons and neutrons, so the protons and nuetrons cancel each other out, resulting in an overall charge of zero.
Does an atom have a charge if the neutrons equals the protons?
It depends on the amount of electrons in the outer shells. The neutrons do not affect the charge of an atom as they are already neutron. There is only a charge if there is a difference in protons and electrons, not protons and neutrons.
Why do atoms usually have no overall charge?
The protons in an atom have a positive charge and the electrons in an atom have a negative charge and these balance each other. Neutrons have no charge so they do not factor into it. It would be like adding positive 4(Protons) and negative 4(Electrons). -4+4=0 The zero represents your "no overall charge".
17 protons equals how many electrons?
17 protons in an atom would equal 17 electrons to maintain a neutral charge.
Why must a neutral atom have the same number or protons and electrons?
The electrons posses negative (-) charge and the protons positive (+). - and + equals 0 and 0 means neutral.So, if the electrons are more than the protons the charge would be negative because the electrons are negatively charged.If the protons are more than the charge would be positive because the protons are positively charged.
Why a neutral atom has the same number of protons and electrons?
To compensate each proton (+1 charge) you need an equal amount of electrons (-1 charge for each) to get a neutral atom.p*(+1) and e*(-1) can only be zero if p equals e .
If helium has 2 protons 2 electrons it is considered what?
Helium with 2 protons and 2 electrons is considered a neutral atom. This is because the number of protons (positively charged) equals the number of electrons (negatively charged), resulting in a balanced charge overall.
When the number of protons in an atom equals the number of electrons the atom is this?
The atom is electrically neutral when the number of protons in the nucleus is equal to the number of electrons surrounding the nucleus. This balance of positive and negative charges results in no overall charge on the atom.
What is true about a atom that has a neutral charge?
An atom with a neutral charge has an equal number of protons (positively charged) and electrons (negatively charged). This balance of positive and negative charges results in the overall charge of the atom being zero.
