Which one of the following series of lines in the hydrogen spectrum arises from transitions down to n2?
The series of lines in the hydrogen spectrum that arises from transitions down to n=2 is known as the Balmer series. This series includes visible light emissions when electrons fall from higher energy levels (n≥3) to the n=2 level. The Balmer lines are characterized by wavelengths that fall within the visible range, producing colors such as red, green, and blue in the spectrum.
What else can I help you with?
Why is n2o3 colored?
Because its molecules contain differences between occupied and unoccupied energy levels of electrons that correspond in energy to part of the visible light spectrum. This causes the gas to absorb a noticeable fraction of some wavelenghts of visible lights while being transparent to others. The unabsorbed wavelengths of light correspond to the color of the gas.
Why potassium permanganate is colored yet it has no d- orbital in Mn?
Potassium permanganate (KMnO4) is colored due to its ligand-to-metal charge transfer transitions, not because of d-orbital transitions. The manganese ion in KMnO4 has empty 3d orbitals, but these are not involved in the color of the compound. The color arises from the interaction between the oxygen atoms of the permanganate ion and the manganese atom.
What alkali metal produces violet flame when mixed with water?
Lithium is the alkali metal that produces a violet flame when mixed with water. This color arises due to the excitation of electrons in the lithium atoms, leading to the emission of light in the violet part of the spectrum.
What is a week interaction involving a hydrogen Atom and a fluorine on oxygen or nitrogen atom?
A weak interaction involving a hydrogen atom and a fluorine atom on an oxygen or nitrogen atom typically refers to hydrogen bonding. In this case, the hydrogen atom, which is covalently bonded to an electronegative atom like oxygen or nitrogen, can form a weak electrostatic attraction with a fluorine atom from another molecule. This interaction arises because fluorine is highly electronegative, creating a partial negative charge that attracts the partially positive hydrogen, facilitating the formation of hydrogen bonds. These interactions are crucial in determining the structure and properties of various biological molecules, such as proteins and nucleic acids.
Identify the epidermal layer in which the following cancers arise a basal cell carcinoma b malignant melanoma c squamous cell carcinoma?
a. Basal cell carcinoma arises in the basal cell layer of the epidermis. b. Malignant melanoma arises from melanocytes located in the basal layer of the epidermis. c. Squamous cell carcinoma arises in the squamous cells of the epidermis, which are found in the upper layers of the epidermis.
Why CoCl4 2 shows a deep blue colour?
because of spin allowed d-d laporte allowed transition
Why are spectrum discontinuous?
The discontinuous nature of a spectrum can be attributed to the fact that it is composed of individual discrete values or levels. Each value represents a specific frequency or energy level within the spectrum, resulting in distinct jumps or gaps between these values. This discreteness arises from the quantization of energy levels in a system, leading to a non-continuous distribution of frequencies or energies in the spectrum.
What is the charge of a hydrogen sulfate atom?
The charge of a hydrogen sulfate atom is -1. This charge arises because the hydrogen sulfate ion, HSO4-, has one more electron than protons, resulting in a net negative charge on the atom.
Why is n2o3 colored?
Because its molecules contain differences between occupied and unoccupied energy levels of electrons that correspond in energy to part of the visible light spectrum. This causes the gas to absorb a noticeable fraction of some wavelenghts of visible lights while being transparent to others. The unabsorbed wavelengths of light correspond to the color of the gas.
How would you classify the following material milk?
Milk is a liquid substance that arises from mammals and is classified as a liquid food item.

What does necessity arises mean?
Same as need arises.
What is the secondmost abundant element in the universe?
Helium is believed to be the second most abundant element in the universe, because the energy of most stars arises from the fusion of hydrogen to produce helium.
what is Helium about?
helium is after haydrogen it means hygrogen is lighter than helium. now the question arises that "Q.1"why we use helium instead of hydrogen coz hydrogen is lighter than helium. Ans.1:hydrogen has 1 electron in its 1st shell and helium has it's complete shell with two electron. When we fill hydrogen in the baloon they form ionic bond... so it is used double...

What is the portion of the stem from which the leaf arises?
The portin of the stem where the leaf arises is called the node.
