<span>Because protons are positively charged and neutrons have no charge then it is safe to say that such an atomic model would have the positive charge concentrated in the center of an atom (option d).</span>
The correct answer among the choices is the last option. <span>Green light has a higher frequency than orange light. Frequency is inversely proportional to wavelength. G</span>reen has wavelengths ranging form 495 to 570 nm and orange has wavelengths ranging from 590 to 620 nm. Speed is said to be directly proportional with wavelength. Higher wavelength means more faster light.
Answer:
In first shell 2 electrons are present and 7 electrons are present in last shell
Explanation:
In Thomson's experiment, he showed that an electrical current can be made to flow from a positive site to a negative site.
It is false, the atomic number is the number of protons and/or electrons in an atom on an element.
