Elements with 2 electrons are called as Group 2 Elements.

As the name says elements with 2 electrons.

Such elements have 2 electrons in their outermost orbit, due to the presence of these 2 electrons in the outermost orbit such elements are not stable.

So, for becoming stable and completing the octet in the outermost orbit the elements need to lose their 2 electrons which are present in the outermost orbit.

Some common examples of such elements is Magnesium, Calcium, and Strontium.

The valency of such elements is 2.

As we know, valency is nothing but the number of electrons which are either lost or taken by the atom for completing their octet.

Due to the fact that sound waves travel further in water than radar and light waves do, sonar, which stands for Sound Navigation and Ranging, is useful for exploring and mapping the ocean.

How does underwater sonar operate?

By sending ultrasonic waves into the water and listening for the returned echoes, a sonar may find these items. The distribution, density, and movement of a school of fish can be seen on the Sonar display at an angle of 360° or 180° in all directions.

Can sonar identify undersea humans?

To "see" in the water, sonar uses sound waves. To find underwater shipwrecks, bodies of people, and other objects, as well as to determine the circumstances of their drowning, sonar is a very valuable tool.

I= 1/L∫Vdt, where I is the current flowing through the inductor, L is the inductor's inductance, and V is the voltage across the inductor, is the formula that determines the inductor current depending on these input parameters. You will frequently come across the expanded formula I= I0 + 1/L∫Vdt.

A passive two-terminal electrical device known as an inductor, also known as a coil, choke, or reactor, stores energy in a magnetic field as electric current passes through it. Typically, an inductor is made out of insulated wire twisted into a coil.

According to Faraday's law of induction, when the current through the coil changes, the time-varying magnetic field induces an electromotive force (emf) (voltage) in the conductor. Lenz's law states that the induced voltage has an opposing polarity (direction) to the change in current that caused it. Inductors so reject any changes in the current flowing through them.

Answer:

A mass spectrometer uses a magnetic field to separate ions based on their mass-to-charge ratio. The mass of an ion can be calculated from its charge, velocity, and the radius of curvature of its path in the magnetic field, using the formula m = (qBv)/(2πr), where m is the mass, q is the charge, B is the magnetic field, v is the velocity, and r is the radius of curvature.

In this case, the magnetic field is 5.00 mT, the charge of the unknown particle is 2e, and its velocity is 100 m/s. The radius of curvature of the ion's path is measured to be 1.67 mm. Plugging these values into the formula above, we get:

m = (2e * 5.00 mT * 100 m/s) / (2π * 1.67 mm) = 0.24 g/mol

Therefore, the mass of the unknown particle is 0.24 g/mol.

To determine which element the particle is, we can use the periodic table to find an element with a mass-to-charge ratio of 0.24 g/mol. The element with the closest match is magnesium (Mg), which has a mass-to-charge ratio of 24.31 g/mol. Therefore, the unknown particle is likely to be a magnesium ion (Mg²⁺).

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy.

So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν. Frequency and wavelength are inversely related to one another, as shown by the equation v = f. For an electromagnetic wave, the connection between frequency and energy is as follows. The electromagnetic wave's energy (E) is equal to its frequency times Plank's constant (h) (f). This relationship is an illustration of a relationship that is directly proportional. The wavelength of the radiation has an inverse relationship with the energy of the photons. A wavelength's frequency and energy (E) drop as it gets longer. You may conclude from these equations that the wavelength gets shorter as the frequency rises. The wavelength lengthens as the frequency drops.
