The wavelength in the nanometer is  9.70 E-22.

Wavelength is the distance among equal points (adjacent crests) inside the adjacent cycles of a waveform sign propagated in space or alongside a wire.

The wavelength is the distance between two wave crests, and it is going to be the same for troughs. The frequency is the number of vibrations that pass over a given spot in a single 2d, and it's far measured in cycles according to 2d Hz.

The wavelength of light determines its shade, and the wavelength of sound determines the pitch. The wavelengths of seen light amplify from approximately seven-hundred nm (purple) to 400 nm (violet). The wavelength of audible sound range from approximately 17 mm to 17 m.

Rutherfordium when decomposes and loses two neutrons, both these rutherfordium isotopes produce neutrons as they undergo their nuclear decay into nobelium.

Rutherfordium's reactivity with the halogens is unclear because so little of it has ever been produced. One would anticipate that it will behave similarly to zirconium and hafnium, which are just above rutherfordium in the periodic table (two places above). After the rutherfordium decays, the distinctive nobelium decay energy and half-life were also seen. Atoms have been created rather infrequently. It is solely employed at this time for research.

The biological function of rutherfordium is unknown. When Rutherfordium, the 104th element on the periodic table, was first artificially created in the 1960s, it sparked a decades-long international debate. The main point of contention was who should get to name the new element. Traditionally, the person who discovers an element is given the privilege of naming it, but this becomes complex when two parties have conflicting claims of discovery.

Solutions 1 and 3 because they are strong acids and a strong base. Option A.

Strong acids and strong bases are completely ionized in an aqueous solution. Weak acids and weak bases also ionize, but only partially and the reaction is reversible. So you know if an acid or base is strong or weak. A simple way to determine strength is to add the acid or base to water. A higher reactivity means a stronger acid or base.

One of the simplest tests to determine whether a solution is an acid or base is the litmus paper test. To do this, dip a special strip of paper so-called litmus paper into the solution and observe the color of the paper. Litmus paper turns red in acidic solutions and blue in basic solutions. Sodium hydroxide is the strongest base because it completely dissociates to form sodium and hydroxide ions. These hydroxide ions are further treated with hydrogen ions by an acid to completely ionize the hydrogen ions.

Given the below compound

Answer: Nothing will happen

Explanation:

Elements want to fill their valence shell with electrons (8).

Referring to both of the table below we will know that the element with that electron configuration is Neon (Ne). It is on the far right side of the periodic table so it contains all 8 electrons in its valence shell. The elements on the right side of the periodic table are called noble gases and are not reactive because they have the maximum number of electrons.

A single electron from the outermost shell of this element will move into the outermost shell of the atom with seven electrons.Nothing will happen in these state.

Electron configurations define the arrangement of electrons around an atom's nucleus. Lithium, for instance, contains two electrons in the 1s subshell and one electron in the 2s subshell, according to its electron configuration, 1s22s1.

We may determine that Neon is the element with that electron configuration by looking at both of the tables below (Ne). It has all 8 electrons in its valence shell since it is on the extreme right side of the periodic table.

Noble gases are the elements on the right side of the periodic table that contain the most electrons and are thus non-reactive.

The globally averaged surface air temperature would decrease if the atmosphere were composed entirely of nitrogen and oxygen. The main greenhouse gases in the atmosphere are water vapor, carbon dioxide, and methane.

 These gases allow sunlight to pass through the atmosphere and then trap some of the heat that radiates back from the Earth's surface. Nitrogen and oxygen are not greenhouse gases, so they would not trap heat in the atmosphere.The global average surface air temperature would decrease because nitrogen and oxygen are both transparent to incoming solar radiation, meaning that less heat would be trapped at the surface of the Earth. Additionally, the greenhouse effect would be weaker without other greenhouse gases like water vapor and carbon dioxide, further cooling the planet.
