Answer:

Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur. It has many more technological applications including MRI scanning (magnetic resonance imaging) and electric bells.

Explanation:

Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment.

A Ca atom (atomic number = 20) is in the ground state. Light is shined on the atom, exciting the most energetic electron. Which

Vikentia [17]

Answer:

The possible quantum numbers for Ca atom when it is in excited

n = 4

l= 1

m =-1,0,1

Explanation:

Given that,

Atomic number = 20

The configuration of Ca

$Ca = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2$

So, The principle quantum number is n =4.

The azimuthal quantum number can take value from 0,1,2...(n-1)

In the ground state, l= 0

When it is excited to p state

Then, l = 1

The magnetic quantum number can take value from l to -l

$m=1,0,-1$

Hence, The possible quantum numbers for Ca atom when it is in excited

n = 4

l= 1

m =-1,0,1
