Outer shell - Study guides, Class notes & Summaries

Gaining vs. Losing electrons - ️️N+1 = Losing electron N-1 = Gaining electron Electrons = electronegative Octet rule - ️️Atoms are most stable when their outer shell is full. The outer shell has to be filled with 8 electrons EXCEPT Hydrogen and Helium with just 2 electrons. Three Physical States of Matter - ️️Solid, liquid, gas Element - ️️Substance that cannot be broken down into other substances by chemical reactions Matter - ️️Anything that occupies space and has a...

PADI Dry Suit DiverWhat is hypothermia? - correct answer The body core temperature dropping below normal. Why can mild hypothermia be a serious problem for scuba divers? - correct answer It interferes with clear thinking, reducing a diver's normal decision-making abilities. It also saps away strength and endurance. How do you avoid hypothermia? - correct answer By always wearing adequate thermal protection before, during and after the dive. If you start to shiver uncontrollably, end the d...

Why do only the outer electrons leave their orbit shells? Answer Only outer electrons leave their orbit shells because electrons farthest from the nucleus are more easily freed from their orbits due to a weaker electrostatic force. What is required to have a balanced (or stable) atom? Answer The number of electrons must equal the number of protons in order to have a balanced atom. List the capacity of each of the first four orbital shells of an atom. Answer Shell: #1 = 2 electrons; #2 = 8 ...
