Answer:
The answer to your question is: The first option.
Explanation:
Outer electron shell because these electrons can be readily exchanged with adjacent atoms As is mentioned in the statement, these electrons can be exchanged easily with adjacent atoms, so this is the right answer.
Innermost electron shell because the electrons can be transferred to the nucleus. Innermost electrons can not react as easily as the outermost, because they are protected by the outermost shells. This answer in not correct.
Middle electron shell because they are intermediate in distance between the nucleus and the adjacent atom that bonds with the atom. In order that an electron can react, it must be located in the outermost shell, it is not an advantage to be in the middle shells. This option is incorrect.
Any electron can exchange with adjacent atoms to form a bond; there is no preference. Not any electron can react with another element, only the electrons in the outermost shell can react, this option is incorrect.
An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35particles<span> in the </span>nucleus<span>) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 </span>particles<span> in the </span>nucleus<span>). Adding or removing a neutron from an atom's </span>nucleus<span> creates </span>isotopes<span> of a particular element.</span>
Yes. A mixture can be made up of just elements without the use of a compound, you can also just use compounds in a mixture without any elements
Visible photon has more energy than a microwave photon. A microwave oven pumps out 1,000 watts of energy or more by generating a whole bunch of photons. Your conventional oven actually puts out even more energy (3,000 watts for an electric, 5,000 for gas). Most of that is infrared, which has less energy than visible light but more than a microwave.Thus the answer is <span>shorter than visible light.</span>
