Answer:
C- A proton has about the same mass as a neutron .
Explanation:
In an atom such as a carbon atom, the masses of the proton and neutrons are the same.
The mass of the electrons is very negligible.
- Protons are the positively charged particles in an atom
- Neutrons do not carry any charges
- Both protons and neutrons have similar masses.
- They contribute the bulk of the mass of the atom.
- The electrons carry negative charges and they have negligible masses.
The mass of protons and neutrons are similar.
Answer:
a list of characteristics that can be used to identify a substance include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.
A moon would be the correct answer.
(a) The nucleus has most of the mass and comprises most of the volume of an atom; false
The nucleus has most of the mass but the volume of an atom is depends on the distance between the nucleus and the position of the electrons.
(b) Every atom of a given element has the same number of protons; true
They may have different number of neutrons and so you have isotopes but the number of protons remain the same for a given element.
(c) The number of electrons in an atom equals the number of neutrons in the atom; false
The number of electrons in an atom equals the number of protons in the atom.
The electrons are negatively charged which compensate the positively charged protons not the neutrons which do not have a charge (they are neutral).
(d) The protons in the nucleus of the helium atom are held together by a force called the strong nuclear force. true
