why transition element have variable valency?​

Answers

Answer 1

Answer:

The elements having d-orbital as penultimate orbital and the outermost s-orbital, like transition metals, show variable valency.

In other words, transition elements show a variable valancy due to involvement of d-orbitlas electron in bonding.

For example :- Mn can show 2 3,4,5,6,7 oxidation states.

Explanation:

This is because they have unfilled d-orbital but filled s-orbital.

For example Iron (Fe) Atomic no 26, so 26 electrons to be filled in different orbital. So the electronic configuration is

(1s)2 (2s)2 (2p)6 (3s)2 (3p)6 (4s)2 (3d)6 this is the way of filling of electrons according to aufbau's principle. But the exact arrangement is (1s)2 (2s)2 (2p)6 (3s)2 (3p)6 (3d)6 (4s)2

So Iron can lose two electrons from the outermost 4s subshell to show a valency of two. Then it can lose another electron from the 3d subshell (penultimate) two show a valency of three. When it shows the valency of two the electron configuration is (1s)2 (2s)2 (2p)6 (3s)2 (3p)6 (3d)6 (4s)0

When it shows the valency of two the electron configuration is (1s)2 (2s)2 (2p)6 (3s)2 (3p)6 (3d)5 (4s)0

And the +3 valence state is stabler than the +2 valence state, because the d-orbital contains 5 electrons (halffilled). As you know fully filled and exactly half filled orbitals are more stable than the orbitals having different no of electrons, i.e. less than half filled and more than half filled but not fully filled.

The transition metals show variable oxidation states. like manganese, Mn shows +2, +4, +6, +7 oxidation states.

Answer 2

Answer:

The Transition Element have their valence electrons in two different sets of orbital that is (n-1)d and NS. ....Thus, Transition Element Show Variable valencies due to involvement of penultimate d shell electrons

How does art travel these days? What effects might this have on modern art?

Answers

Answer:

from a chemical point of view, time really does change art. Mediums darken, some colours fade and the support material adjusts. The biggest change is that we the viewer are placing on the art piece. Sculpture may be physically worn away by our caressing, leaving the intended platina polished back to a different colour.

Art influences society by changing opinions, instilling values and translating experiences across space and time. Research has shown art affects the fundamental sense of self. Painting, sculpture, music, literature and the other arts are often considered to be the repository of a society's collective memory.

Art travels these days by social media with people posting their art on apps like Instagram and Twitter this will inspire a lot of other people to make art which makes a lot of good new art go into the main stream but this could also have a negative affect by a lot of bad art going in which can lower the artist confidence

Shade can refer to any mixture of color with black one to that is used to give the artwork a three dimensional effect, which seems very attractive and enhance the look for the painting.

What is tenebroso? Name a painter and

Answers

Martyrdom of St Andrew by Jusepe de Ribera

this painting and artist is one of the most famous tenebroso paintings

Tenesbroso is used to define a certain style of painting in which important elements like hands and faces are highlighted in contrast to a background that is primarily dark.

The early 17th century saw the adoption of the method by artists who were influenced by the Italian painter Caravaggio (1571-1610), notably the French painter Georges de La Tour, the Dutch painters Gerrit van Honthorst and Hendrik Terbrugghen, and the Spanish painter Francisco de Zurbarán.

What do you mean by Painter?

Painter is the artist who used to paint pictures, portraits and so on.

Tenebroso is an Italian word that means "black" or "gloomy." The term "Tenebroso" in fine art refers to a painting technique in which dark colors predominate over light ones and stark contrasts between light and dark regions are extremely expressive and dramatic.

Sometimes the Italian word "chiaroscuro" is used to describe this style of painting. Tenebrism is the name of the art movement that abused chiaroscuro, and tenebrists are its adherents.

Therefore, Tenesbroso is a term used to describe a particular painting style in which key features such as hands and faces are emphasized in contrast to a predominantly dark background.
