Ionization energy: the energy required to remove an electron from a neutral atom. Electron affinity: the energy change when a neutral atom attracts an electron to become a negative ion.
What qualifies someone to be one is someone who systematically gathers and uses research and evidence making a hypothesis and testing it to gain and share understanding and knowledge.
but the role of a scientist is..: scientists use their resources to bring out change, wether it is change in medicine, improvements in the environment, or creating efficient fuels
I rlly hope this helps tysm
The electrons are transferred from potassium to sulphur, in this reaction, potassium is being oxidised and sulphur is being reduced. Two potassium atoms each lose one electron forming K+ ions. Sulphur gains two electrons forming S2-/2- ions. The resultant formula will be: K2S, bonding in this compound is ionic.
Aerial fireworks are usually manufactured as a shell that is made up of four parts. The container consists of pasted paper. The fuse allows the shell to reach the desired altitude before exploding. A bursting charge made of black powder (like a firecracker) is at the center of the shell.
By doing fractional distillation
