Answer:
No
Explanation:
Argon has a larger atomic radius
Matter can neither be created or destroyed, it may seem as though burning destroys matter but the same amount (mass) of the matter still exists. The matter changes into a new substance(s) such as ash, gas and water vapor.
Explanation:
As you move across the periodic table, the number of protons and neutrons increases but the number of orbital levels of the period remains the same. The atomic radii therefore decrease, across the period, because the increase in proton number causes an increased pull of the orbital electrons bringing them closer to the nucleus.
As you move down a group in a periodic table, the number of orbital levels increase. The effective nuclear charge of the nucleus of the atoms decreases due to the increased number of orbital levels that shield the valence electrons from the attractive force nucleus.
It would have 8 neutrons. Since the atomic number = the number of protons in the atom, oxygen has 8 protons. If the atomic mass is made up of protons and neutrons, then it would have 8 neutrons as well (8+8=16)
Answer : Density of any particular matter remains the same at any concentration at any weight.
Density does not varies with the concentration. The formula for density is mass / volume.
So if the mass changes the density will change accordingly, also if the volume changes the density will get changed.
because, of the above reasons density is referred as a characteristic property of matter.
