what is known as electronegativity and mention how the electro negativity vary long the periods and down the groups..please i need answers quickly!​

Answers

Answer 1

Answer:

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

Answer 2

Explanation:
Before I go on, I want to bring up that it's not just electronegativity that is affected as you go across a period or up and down a group. Ionization energy and atomic radius also fluctuate.
Here's a diagram:

As you can see, electronegativity increases as you go across a period, while electronegativity decreases as you go down a group. However, if this is true (which it is), we can also say many other factors occur, such as:
As you go across a period from left to right, electronegativity increases, ionization energy increases, and atomic radius decreases. In order for energy to increase, radius must decrease.

As you go up and down a period, electronegativity decreases, ionization energy decreases, and atomic radius increases. In order for energy to decrease, radius must increase.

Electronegativity is the force/energy required to acquire electrons and form negative ions during chemical reactions. (definition credit: from my computers dictionary).

Ionization Energy is the complete opposite. Ionization is the force/energy required to remove electrons from an ion. These strive to make cations while electronegative ions usually involve anions (hence the phrase electronegativity).

What is atomic spectroscopy?

The investigation of the electromagnetic radiation that atoms absorb and release is known as atomic spectroscopy. Atomic spectroscopy, specifically the electromagnetic spectrum or mass spectrum, is used to determine the elemental compositions of substances since distinct elements have distinctive spectra.

Depending on the type of spectroscopy being utilized or the atomization source, it can be divided. The primary distinction in the latter instance is between optical and mass spectrometry. Although substantially more difficult, mass spectrometry typically provides significantly higher analytical performance.

Electrons can migrate between orbitals, but doing so requires them to either absorb or emit energy equivalent to the difference in energy levels between the quantized orbitals of their respective atoms.

A. Adding another bulb will make the two of them light a little less brighter since the electrical flow is divided into two making them work.

B. There is a possibility that the flow of electricity maybe little due to the thickness of the wire. There could also be a rise in the temperature of the cell and the bulb.

C. The Bulb will shine brighter because of the extra power or electricity provided! Also, if the voltage is too much, expect the bulb to burn out or sadly, explode.
