I think the first one is negative electrons. The second one might be to achieve a higher energy state
Acids and bases are fairly important for the fact that they are very essential to the human body. As well as they balance the Ph levels in our body. You can use acids and bases to nurtralize eachother aswell
The answer is threatening behavior by predators. Reason is that it is used as a self defense strategy.
Phosphorus - P - Protons = 15, Electrons = 15, Neutrons = 16 - Non-Metal
Lithium - Li - Protons = 3, Electrons = 3, Neutrons = 4 - Metal
Nitrogen - N - Protons = 7, Electrons = 7, Neutrons = 7 - Non-Metal
Copper - Cu - Protons = 29, Electrons = 29, Neutrons = 34 - Metal
Neon - Ne - Protons = 10, Electrons = 10, Neutrons = 10 - Non-Metal
sorry i don’t know about the other questions but i thought i could help with the table!
Additional Info:
number of protons = atomic number
number of electrons = atomic number
number of neutrons = mass number - atomic number
