Answer:
The first valence electron is removed.
Explanation:
Ionization energy is the energy that is needed to tear out the last electron of an atom in its ground state or gaseous state.
A(g) + IE ----> A+(g) + 1e-
When we talk about starting an electron we refer to the last valence electron, since it is the one that is furthest from the atomic nucleus, the one that does not feel attracted. As the question asks us the opposite, the ionization energy is going to be extremely high, if the electron to be removed occupies the first valence layer, since it is totally attracted to the nucleus.
Answer:
D: Electromagnetic
Explanation:
Chemical energy is the energy in chemical bonds which is a type of potential energy, eliminating both B and C. While kinetic energy is the energy of motion, photons are a wave/ particle so thinking it would have kinetic energy wouldn't be your fault but light is on the electromagnetic spectrum making D the most likely answer.
The mass is conserved, so it stays the same, 450g
