4p, 3d, 3p, 3s, 2p, 2s and 1s orbitals may be occupied during de-excitation.<span />
Distance s=347 meters
time t=134 sec.
speed =s/t=347/134=2.5896 m/s nearly
<em>The number of protons and electrons in a neutral atom of the element are;</em>
D. 29 protons and 29 electrons
<u>The atomic number of an element is equal to the number of protons in the nucleus of each atom of that element.</u>
<u>Thus copper has an atomic number of 29, all atoms of copper will have 29 protons.</u>
The more protons you add, the more positively charged the atom becomes
the charge of an atom determines what kind of an atom it is <span />
