Answer/Explanation:
quantum of energy is important because the energy of a particle, and also how long it has had that energy, with infinite precision. Quantum, in physics, discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property. the term also applicable to quanta of other forms of electromagnetic energy such as X - rays and gamma rays.
Answer:
B
Explanation:
alkene is no polar compounds
and insoluble in water
Answer:
The correct answer is option D which is the decreasing order of conductivity is Mn, O, Ge.
Explanation:
You can easily answer this if you know the periodic trends. For the property of electrical conductivity, it decreases across a period and decreases also down a group. Thus, the most conductive element must be Mn, while the least conductive one is Ge. So, the answer is: -Mn, O, Ge
The periodic trend of reactivity depends on whether the elements are metals or nonmetals. For metals, reactivity increases down a group and from right to left across a period. Nonmetals do the opposite. For nonmetals, reactivity increases up a group and from left to right across a period. Therefore, the rank is as follows:
Fluorine
Selenium
Neon
Hope this answers the question. Have a nice day.
