The neutron has no charge because it is a neutral particle.
Hope this help you!!! :))
Answer:
Energy: Radio Waves least, Infrared 2nd,, Blue light 3rd, Gamma Rays 4th
Wavelength: Gamma Rays smallest wavelength, Blue light 2nd, Infrared 3rd, Radio waves 4th
Frequency: Radio Waves smallest frequency, Infrared 2nd, Blue Light 3rd, Gamma Rays 4th
Explanation:
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
Based on the Zeroth Law of Thermodynamics, two systems are at equilibrium when there is no heat flow, q, between the systems.
Answer:
D. A²⁺
Explanation:
Element from Group 2A -
The element of group 2A are known as the alkaline earth metals ,
The elements of this group are - beryllium (Be) , magnesium (Mg) , calcium (Ca) , strontium (Sr) , barium (Ba) , and radium (Ra).
The valence shell of these elements have two valence electrons and therefore , if the element need to stabilizes itself , it need to lose these two electrons and attain noble gas configuration,
Therefore ,
After losing the two electrons , the element becomes A²⁺.
Hence , the ions are symbolized as A²⁺.
