Answer:

For a: The isotopic symbol of the above atom will be $_{53}^{131}\textrm{I}$

For b: The isotopic symbol of the above atom will be $_{77}^{192}\textrm{Ir}$

For c: the isotopic symbol of the above atom will be $_{62}^{153}\textrm{Sm}$

Explanation:

The isotopic representation of an atom is: $_Z^A\textrm{X}$

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

For a: Iodine-131

Atomic number of iodine = 53

Mass number of iodine = 131

Symbol of iodine = I

The isotopic symbol of the above atom will be $_{53}^{131}\textrm{I}$

For b: Iridium-192

Atomic number of iridium = 77

Mass number of iridium = 192

Symbol of iridium = Ir

The isotopic symbol of the above atom will be $_{77}^{192}\textrm{Ir}$

For c: Samarium-153

Atomic number of samarium = 62

Mass number of samarium = 153

Symbol of samarium = Sm

The isotopic symbol of the above atom will be $_{62}^{153}\textrm{Sm}$

Which observation provided Albert Einstein the clue that he needed to explain the photoelectric effect? Light is made up of extr

Aliun [14]

The correct answer is

Energy of electrons depends on light’s frequency, not intensity.

As per photoelectric effect, if we incident a light on metal surface it will results into emission of electron from it

if we increase the number of photons the number of electrons will increase however if we increase the frequency the number of photons will not increase

While if we increase frequency the energy of electrons will increase as

Energy of photon = Work function of metal + kinetic energy of electrons

Which best describes an experiment that had good scientific design? Most of the methods were different for each trial within the

Kay [80]

Answer: Each trial was repeated several times during the experiment.

A scientific design refers to a scientific plan or methodology, which needs to be followed to perform a experiment so as to obtain accurate and appropriate result matching with the situation of the hypothesis. Each trial was repeated several times during the experiment best describes an experiment that had a good scientific design because trials in an experiment brings either concordant or consistent results or inconsistent results. The concordant results suggests that the methodology applied is correct, and inconsistent results show that methodology applied is incorrect.
