Use the periodic table to determine the electron configuration for aluminum (AI) and arsenic (As) in

Chemistry
1 answer:
Harlamova29_29 [7]3 years ago
4 0

Answer:

Aluminum; [Ne]3s²3p¹

Arsenic; [Ar]3d¹⁰4s²4p³

Explanation:

<em>Aluminum</em>

From the periodic table, we have that aluminum, Al, is located in period 3, and group 3A of the periodic table

Therefore, the noble gas that comes before aluminum in the periodic table is neon Ne

The electronic configuration of aluminum is 1s²2s²2p⁶3s²3p¹

The electronic configuration of neon is 1s²2s²2p⁶

Therefore, the electronic configuration of aluminum in noble gas notation (Ne) is therefore;

[Ne]3s²3p¹

<em>Arsenic</em>

Arsenic is located after argon, Ar on the periodic table

The electronic configuration of arsenic is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³

The electronic configuration of argon is 1s²2s²2p⁶3s²3p⁶

The electronic configuration of arsenic in noble gas notation (Ar) is given as follows;

[Ar]3d¹⁰4s²4p³

A. element with the highest electronegativity.
Bess [88]

Answer:

Fluorine

Explanation:

Fluorine is assigned the oxidation number of -1 because it attracts the electrons in the bond more strongly than carbon does. Fluorine appears to have an extra electron, -1 oxidation number.

Fluorine is the most electronegative element on the periodic table.

Give the chemical symbol of an element in the third period (row) of the periodic table with four 3p electrons.
Ann [662]

<u>Answer: </u>The chemical symbol of the element is Sulfur.

<u>Explanation:</u>

The element which is present in third period of the periodic table having four 3p electrons is Sulfur. Sulfur is the 16th element of the periodic table which has 6 valance electrons.

The electronic configuration of this element is:  [Ne]3s^23p^4

This element is considered as a non-metal because it will accept electrons in order to attain stable electronic configuration.

Hence, the chemical symbol of the element is Sulfur.

Two cars travel next to each other. One speedometer reads
Yanka [14]

Answer:

The pair of arrows which represents the relationship of speeds of the two cars is;

The second option as shown in the attached drawing

Explanation:

The given parameters are;

The reading on the speedometer of one car = 20 m/s

The reading on the speedometer of the other car = 72 km/h = 20 m/s

The blue arrow = 20 m/s

Therefore, given that the speeds of both cars are equal (20 m/s = 72 km/h = 20 m/s),  the pair of arrows that represent the relationship of speeds of the two cars is two equal length blue arrows which is the second option

The attached diagram showing the pair of arrows that represents the relationship of speeds of the two cars is drawn using Microsoft Visio.

Click oil basics to explore the natural resources needed for the production of plastics. use the information to answer the quest
GaryK [48]

The ingredients that is important in making plastics is natural gas plant liquids.

Natural gas liquids (NGLs) are components of natural gas which are separated from the gas state in the form of liquids. They many applications including; plastic production, inputs for petrochemical plants, they are also burned for space heat and cooking, and can also be blended into vehicle fuel.

In the manufacturing of plastics, come components of NGLs are used. And for this case, ethane. Ethane is used in the production of ethylene which are passed through pressure and catalyst to be turned to plastics like polythene.

The reason why they are mostly used in the manufacturing plastics than other resources like crude oil is that it is much cleaner.
