If it is assumed that an alpha particle moves at a velocity of 1.5 x 10 m/s, calculate the kinetic energy of the alpha particle. A. 1.50 10-12 J
B. 7.47 x 10-13 J
C. 1.00 x 10-19 J
D. 5.01 x 10-20 j

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
