Answer:
True
Explanation:
Electrons that are in the first energy level (energy level 1) are closest to the nucleus and will have the lowest energy. Electrons further away from the nucleus will have higher energy. An atom's electron shell can accommodate 2n2 electrons, where n is the energy level.
Explanation:
hope this helps you with the question
Answer: increasing volume
Explanation: adding a catalyst would increase reaction time and increasing INCREASING concentration definently makes reaction time alot faster increasing pressure actually makes it more concentrated, so no it is not
The isotopes of an element differ in the number or neutrons whereas the number of protons or electrons of a neutral atom stays the same. The molar mass of the element is based on the percent abundances of different isotopes and the individual molar mass of each isotope.
