In chemistry, "chemical properties" of elements usually refers to the electron affinity of an atom (number of valence electrons) This is because atoms with the same number of valence electrons will form similar compounds with other atoms, and undergo the same types of reactions.
Out of this list: He, Ne and Ar are all group 18 elements (Noble gases)
Therefore they have similar chemical properties.
C) 5 protons, 5 electrons, and 6 neutrons
Answer:
Unlike other noble gases, which are highly nonreactive, Kr and Xe have non-zero values of Electronegativity (3.00 and 2.60, respectively) because they do form compounds: indeed, the electronegativity is a fundamental property of atoms that defines how strong their pull on shared electrons is.
In an automobile engine, fuel is burned to convert chemical energy into __ energy. This energy is then changed into __ energy.
1 ) Heat
2 ) Mechanical
"In an automobile engine, fuel is burned to convert chemical energy into "heat" energy. This energy is then changed into "mechanical" energy"
(Goes from Chemical energy, heat energy, to mechanical energy.)
