Lines in one spectral series can overlap lines in another is rydberg
In several chemical elements, the Rydberg formula is used to compute the wavelengths of spectral lines.
<h3>
What causes lines in a line spectrum?</h3>
A spectral line is similar to a fingerprint in that it can be used to identify the atoms, elements, or molecules in a star, galaxy, or cloud of interstellar gas. When we use a prism to split incoming light from a heavenly source, we often observe a rainbow of colours crossed by definite lines. It's worth noting that spectral lines can appear in other parts of the electromagnetic spectrum, however we can't use a prism to assist us identify them.
Emission lines are distinct coloured lines that appear on a black backdrop and correspond to certain wavelengths of light emitted by an item.
Absorption lines are visible as black bars.

Barium can form ions with a +2 charge and it is called a cation.
Ex:- Ba(s)+2HCl(aq)→BaCl2(aq)+H2(g)
In this redox reaction,
initially, barium shows 0 (s) oxidation no. and after forming the product its oxidation no. changes to +2 (in aq).
When a metal loses electrons and a nonmetal gets those electrons, cations (positively charged ions) and anions (negatively charged ions) are created.
<h3>Ionic bonds are created when a metal and a nonmetal interact. The position of an element on the periodic table can frequently tell you what charge an ion generally carries:</h3>
- the alkali metals (the IA elements) lose a single electron and form a 1+ charge.
- the alkaline earth metals (IIA elements) lose two electrons and form a 2+ cation.
- IIIA family member aluminum loses three electrons to become a 3+ cation.
- Seven valence electrons are shared by all of the halogens (VIIA elements) and each of them has a single negative charge, forming an anion.
- The VIA elements pick up two electrons to create 2- charged anions.
- The VA elements pick up three extra electrons to create 3- charged anions.

Answer:
Triple the Mn half reaction and double the Fe half reaction
Explanation:
Because...we have to balance the number of electrons(e)...which will be eliminated from the equations and they will be combined
Answer:
the number of shielding electrons
Explanation:
Effective nuclear charge is estimated from slaters rules. It is the nuclear charge an electron actually experiences in its orbit and it depends on the number of screening electrons. Slaters rule is a set steps that obtains the effective clear charge using a screening or shielding constant which depends on the orbital of the screening electrons.
