Incorrect Placement of Element: Iodine

Explanation:

1. Introduction:
In the given options, we need to identify the element that is not correctly placed based on its properties and characteristics. Let's evaluate each option to find the correct answer.

2. Evaluation of Options:
a) Aluminium:
- Aluminium is a metal that belongs to Group 13 (or Group IIIA) of the periodic table.
- It has an atomic number of 13, indicating that it has 13 electrons.
- Aluminium tends to lose three electrons to achieve a stable electron configuration like its nearest noble gas, neon.
- Therefore, the statement that aluminium tends to lose three electrons is correct.

b) Iodine:
- Iodine is a nonmetal that belongs to Group 17 (or Group VIIA) of the periodic table.
- It has an atomic number of 53, indicating that it has 53 electrons.
- Iodine tends to gain one electron to achieve a stable electron configuration like its nearest noble gas, xenon.
- The statement in the given option that iodine tends to gain two electrons is incorrect.
- Therefore, this option is the correct answer.

c) Silicon:
- Silicon is a metalloid that belongs to Group 14 (or Group IVA) of the periodic table.
- It has an atomic number of 14, indicating that it has 14 electrons.
- Silicon tends to share four electrons to achieve a stable electron configuration.
- Therefore, the statement that silicon has a valency of four is correct.

d) Plutonium:
- Plutonium is a transuranium element that belongs to the actinide series of the periodic table.
- It has an atomic number of 94, indicating that it has 94 electrons.
- Plutonium is a radioactive element that does not occur naturally in significant quantities on Earth.
- Therefore, the statement that plutonium is a transuranium element is correct.

3. Conclusion:
Based on the evaluation of each option, it can be concluded that the element which is not correctly placed is iodine as it tends to gain one electron, not two electrons as mentioned in the given option.

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescence microscopy.Q. Wavelength of electron as wave at accelerating voltage 200 keV is
