Answer:
wheres the question or picture
Explanation:
Answer:
The Rutherford atomic model stated that an atom is mostly an empty space that consist of nucleus and electrons, where nucleus is positively charged and electrons are negatively charged.
<em>But Rutherford atomic model missed to add the quantum mechanics or energy level for electrons. Rutherford was unable to make understand the planetary movement of electrons around nucleus and later Bohr's model explained it.</em>
Hence, Rutherford's model of the atom missed to explain the planetary movement of electrons around nucleus.
Ionization energy is the energy required to remove an
electron from an atom. Meanwhile, Electron affinity is the energy required to
add an electron to an atom. So we can see that the two are opposite variables.
However, they both refers to general attraction of an atom for “electron”.
"Electric charge: the proton and electron are electrically charged, while the neutron is not. The proton and electron, however, are oppositely charged. Role in the atom: Protons and neutrons are closely bound together in the nucleus of an atom, while electrons are spread out around the nucleus."
The answer is D) one unit of a balanced chemical equation
