Battery,and i think the light bulb because it depends how much energy the light bulb needs
Answer:
True.
Explanation:
Vibrational molecular levels are those energy levels with which atoms are free to vibrate about each other. Like all vibrational motion, this level is governed by quantum mechanics.
The electronic energy levels of a molecule are determined by the orbit of the electron.
The electronic energy level gap are the greatest energy gaps in a molecule. This is because it is a lot more difficult for an electron to transition from one orbital to another. It is in fact easier for it to vibrate about its mean position than for it to jump from one orbit into another.
Furthermore, in order of band gap size, the various energy levels can further be organized below:
Rotational Transition < Vibrational Transition < Electronic Transition
1-20 cm-1 2000-4000 cm-1 10000-50000 cm-1
Answer: A) Nonmetal carbon shares valence electrons with each nonmetal chlorine forming four covalent bonds.
Explanation:Carbon has atomic no 6 and has 4 valence electrons. It can only share electrons as it is difficult to gain or lose 4 electrons to complete it's octet.
Chlorine has atomic no 17 and has 7 valence electrons and need one electron to complete its octet.
Thus carbon will share 4 electrons, one each with four chlorine atoms to form carbon tetra chloride.
Covalent bond is formed by sharing of electrons between atoms.
Ionic bond is formed by transfer of electrons between atoms.
