Answer:

Answer: First Level = 2, Second Level = 4. Explanation: Carbon has the atomic number of 6. This means that it has 6 electrons. Valence electrons are organized by shells or levels. Each level has a specific number of electrons that it can hold. The first level can only hold 2 electrons. Since carbon has more than 2 electrons, carbon must have more than one level in its' electron cloud. The second level can hold 8 electrons. Since 2 electrons went into the first level of the cloud, the remaining 4 will go into the second level of the cloud. Note: the outermost level of the electron cloud does not need to be full.
