Which set of numbers gives the correct possible values of I for n = 2?
Marysya12 [62]

Answer:

0,1

Explanation:

There are four quantum numbers:

Principal quantum number (n)

Azimuthal quantum number (l)

Magnetic quantum number (ml)

Spin quantum number (ms)

All these four quantum numbers gives complete information about an electron like its spin, shells, subshells and orbitals.

For example:

If n=2 than possible sets of quantum numbers are:

Azimuthal quantum number (l)

The azimuthal quantum number describe the shape of orbitals. Its value for s, p, d, f... are 0, 1, 2, 3. l= n-1

(n-1)

2-1 = 1

For n=2 there are two subshell s and p.

s = 0

p= 1

Magnetic quantum number (ml)

It describe the orientation of orbitals. Its values are -l to +l. For l=1  the ml will be  -1 0 +1

Spin quantum number (ms)

The spin quantum  number tells the spin of electron either its clock wise (+1/2) or anti clock wise (-1/2).

If the electron is added in full empty orbital its spin will be +1/2 because it occupy full empty. If electron is already present and another electron is added then its spin will be -1/2.

What is the definition of light in one sentence
bulgar [2K]

The dictionary definiton of light is:

the natural agent that stimulates sight and makes things visible.

I'll paraphrase/give a scientific definition:

Light is made of subatomic particles called photons, which jumps electron shells when they're excited, effecting the electromagnetic spectrum, creating visible light.

Hope this helps. Might not as I'm not perfect on this topic yet.

It is important to understand the differences between chemical and physical changes. Chemical changes result in new substances,
Marysya12 [62]

Answer:

Melting of ice

Explanation:

A physical change is one in which just the physical properties of the matter is altered. Most phase changes reaction falls under this type of change.

  • Examples are boiling, melting, freezing, condensation, sublimation, magnetization of metals, breaking glass, cutting wood.
  1. No new kinds of matter is formed.
  2. The process is reversible
  3. No change in mass
