Answer:

If it loses to electrons the net charge will be +2. If the atom instead gains 4 electrons, the net charge will be -4.

Explanation: When an atom loses electrons( which are negatively charged), it turns into a cation. This means since there is more protons(which are positively charged) than electrons, the charge is positive. The charge is positive and than the number of electrons lost. It is the exact opposite for gaining electrons.

natka813 [3]
Religion and science are fundamentally incompatible. They disagree profoundly on how we obtain knowledge of the world. Science is based observation and reasoning from observation. Religion assumes that human beings can access a deeper level of information that is not available by either observation or reason.

Can someone please help me with this? I would appreciate it.
Luba_88 [7]

Answer: State

Explanation:

The rock on the left is more shiny than the right, so that’s incorrect.

The rocks are not the same color, so that’s also incorrect.

Even though you can’t feel the textures, the right rock looks grainy and the left on doesn’t.

They both are solid, so that is the correct answer.
