The Noble Gases are the most unreactive b/c its outermost shell completes the energy level and is stable enough.
Elements in the each group have the same number of valence electrons.

Answer:
3600 J
Explanation:
Kinetic energy of an object is the energy posses by an object solely due to its motion.
It can also be defined as the amount of work that can be done when an moving object come to test.
Kinetic energy of an object can be calculated by the equation,
K.E. = ½mv²
Where m = mass, v = velocity
So you get,
K.E. = ½×0.5×(120)² = 3600 J
Out of The following speed is the same for all kinds of electromagnetic waves.
Electromagnetic waves travel at the same speed through space. That speed, also known as the speed of light is approximately 300 million meters per moment which are 3.0 x 108 m/s...Although all electromagnetic waves travel at the same speed over space, they may vary in their wavelengths, frequencies, and energy levels. Wavelength is the distance between comparing focuses of adjacent waves. Frequencies of electromagnetic waves run from thousands of waves per second to trillions of waves per second. The energy of electromagnetic waves depends on their frequency. Low-frequency waves have small energy and are ordinarily safe. High-frequency waves have a lot of energy.

The answer is evolution. When a specifies evolves over time they change and adapt to their environment.
Kinetic energy is the energy that an object has because of its motion. The molecules in a substance have a range of kinetic energies because they don't all move at thesame<span> speed. As a subtance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
