Guy that said it was DNA was right i just took the test to so another words your answer is Letter A DNA have a nice weekend! <span />
Yes because when they heat up you sweat, and when they cool down they would probably separated because you are at your normal temperate
Answer:
between the 2 and the 3 shell
Explanation:
when a gain of energy is the displacement of the electrons in a layer of low-energy shell high-energy, and here we have the 2nd shell is the shell of low energy, and 3 shell the shell is high-energy.
It’s fluorine it has a big jump from the 6th to 7th ionisation energy.
It’s electronic configuration is 1s2 2s2 2p5 as it has 9 electrons and 7 electrons in outermost shell.
Therefore it’s in group 7, as after the 7 electrons are removed, the 8th electron is removed from a quantum shell closer to the nucleus.
This results in greater ionisation energy due to stronger electrostatic forces of attraction between positively charge nuclei and electrons ( + shorter distance)
