Without doing any calculations, which transition in the hydrogen atom has the shortest wavelength?

1 answer:

6 0

The n=2 --> n=1 transition in the hydrogen atom has the shortest wavelength. In addition, microwave has a highest frequency wave. In finding the limiting reagent, grams divided by the molar mass and the answer will be divided by the coefficients and the lowest amount is the limiting reagent.

What is a cation and where can you find it on the periodic table?

Maslowich

Answer:

A cation is an ion with fewer electrons than protons. Therefore, it has a positive charge. The electric charge on a proton is equal in amount to the charge on an electron. Anions are atoms or radicals (groups of atoms), that have gained electrons. Since they now have more electrons than protons, anions have a negative charge. Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).

Explanation:

An anion and cation cannot be specifically found on the periodic table.

Give the nuclide symbol for an atom that has<br> mass number 64 and 35 neutrons.

azamat

The mass number represents the summation of the number of protons and the number of neutrons in the nucleus of an atom.
We are given that the mass number is 64 and that the number of neutrons is 35. Therefore:
number of protons = 64 - 35 = 29 protons

In ground state, number of protons in an atom is equal to the number of electrons. Therefore,
number of electrons = 29 electron

Using the periodic table, we will find that the element that has 29 electrons in ground state is copper.
The nuclide symbol of copper is shown in the attached image.

taurus [48]

Answer:

The higher your price, the less volume you have to produce for a given dollar amount of profit! Even a small price increase can generate significant additional profit. ...
