Magnesium is able to ____ copper, and copper is able to ____ magnesium.
sveticcg [70]

Answer:

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Oxidizing agents:

Oxidizing agents oxidize the other elements and itself gets reduced.

Reducing agents:

Reducing agents reduced the other element are it self gets oxidized.

In given example,

Magnesium is able to <u>reduced</u> the copper and copper is able to <u>oxidized</u> the magnesium.

Zinc is able to <u>oxidized</u> the magnesium and magnesium is able to <u>reduced</u> the zinc.

Copper is able to <u>oxidized</u> the zinc and zinc is able to <u>reduced</u> the copper.

using the aufbau principle,write the electronic configuration for the ground state of the atom having atomic number 1 to 30​
Elina [12.6K]

Aufbau principle:

Electrons are added one at a time from the lowest energy orbitals available until all the orbitals are filled.

According to the Aufbau principle, electrons fill lower energy orbitals first.

(i) Boron (Z = 5)

Electronic configuration =  

(ii) Neon (Z = 10)  

Electronic configuration =  

(iii) Aluminium (Z = 13)  

Electronic configuration =  

(iv) Chlorine (Z = 17)

Electronic configuration =  

(v) Calcium (Z = 20)  

Electronic configuration =
