Which of the following statements are true? Check all that apply. Atoms with the same atomic number have the same number of elec
trons Atoms with the same atomic number have the same number of neutrons Atoms with the same atomic number can have different numbers of electrons Atoms with the same number can have different numbers of neutrons
Two correct answers (the first one and the last one listed):
<em>Atoms with the same atomic number have the same number of electrons. </em>
<em>Atoms with the same atomic number can have different numbers of neutrons.</em><em> </em>
Explanation:
There are two correct answers:
<em>Atoms with the same atomic number have the same number of electrons. </em>This is because neutral atoms have the same number of electrons than of protons in the nuclei. And the number of protons in the nucleus characterize the particular element and is called the "Atomic number."
and
<em>Atoms with the same atomic number can have different numbers of neutrons.</em><em> </em>These constitute the isotopes of the element characterized by the given atomic number.
It could have been a parade ceremony, but, if you notice the vehicle's hazard lights or an emergency vehicle ahead, it is common sense to figure that they is a collision scene nearby.
I beleive she isnt doing any work due to holding the box motionless, you must be exerting a force in the direction of the box motion. If she is just standing there holding the box their isn't no work becuase no distance has been covered. work = force = distance.
