Answer:
The first ionization energy is the energy it takes to remove an electron from a neutral atom.
hope it is helpful :)
Answer:
C.) 35
Explanation:
The mass is made up of the total protons and neutrons in an atom. Protons and neutrons both have a mass of 1 amu. Electrons are not included in this measurement because they have an insignificant mass (practically 0).
(17 protons x 1 amu) + (18 neutrons x 1 amu) = 35 amu
Therefore, if an atom contains 17 protons and 18 neutrons, the mass should be 35 amu.
I think 5.50 M x 35.0 mL x molar mass of RbOH = mass (g)
Answer:
Explanation:
scientific notation of 0.000467 is
4.67*10^-4
Metal solids contain a positively-charged cation surrounded by a "sea" of delocalised, negatively-charged electrons.
The electrons are able to move freely, and hence transfer kinetic energy throughout the implement at a much quicker rate than non-metals.
Plastic is made of non-metals (Mostly carbon and hydrogen) and therefore is a poor thermal conductor.
Therefore, by coating the metal utensil in plastic, the rate of heat energy transfer to the person in contact's hand is decreased.
