The ground-state electron configurations of Cd^{2+} transition metal ions are diamagnetic [Kr] 4d^{10}. The ion is diamagnetic because there all electrons are paired.

<h3>What is Diamagnetic?</h3>
  • A magnetic field repels diamagnetic materials because it induces an opposing magnetic field in them when it is applied, which produces a repelling force.
  • In contrast, a magnetic field draws paramagnetic and ferromagnetic materials together.
  • All materials experience the quantum mechanical phenomenon known as diamagnetism, which is the only source of magnetism in a material.
  • The magnetic dipoles within paramagnetic and ferromagnetic materials exert an attracting force that outweighs the modest diamagnetic force.
  • Diamagnetic materials have a magnetic permeability that is less than vacuum, or 0.
  • Although superconductors behave as strong diamagnets, diamagnetism is often a modest effect that can only be observed by sophisticated laboratory equipment.

If the pressure of a gas is 100 kPa when the volume is measured to be 500 mL. What pressure would need to be exerted to have the
Korvikt [17]

Answer:

p2=125 kpa

Explanation:

Using Boyle's law

p1 x v1 = p2 x v2

p1=100kpa

v1=500ml

p2=?

v2=400ml

p2= (100x500)\400

p2=125 kpa

How much heat is needed to raise the temperature of 100g of an iron from 25°C to
Black_prince [1.1K]

Answer:

382.5J

Explanation:

<em>Use the formula:</em>

E = mcΔθ or Q = mcΔT

m = 100g

c = 0.45 J/g°C

ΔT or Δθ = 110 - 25 = 85°

<em>Sub in the values:</em>

E = 100 × 0.45 × 85

= 382.5J

jolli1 [7]

Becquerel  did not discover that the amount of exposure on the paper was proportional to the amount of uranium that was present in the rocks

<h3>What is radioactivity?</h3>

The phenomenon of radioactivity was discovered by the French scientist Henri Becquerel in 1896 when he placed photographic paper in a drawer with some radioactive rocks.

We have to note that Becquerel did not discover that the amount of exposure on the paper was proportional to the amount of uranium that was present in the rocks hence the stetement is false.

One atom of an element possesses 80 protons, 80 electrons, and 121 neutrons. Given this information, what is the atomic mass of
IRINA_888 [86]

Answer:

I think the answer is 4) 41

Explanation:

APE= atomic number, proton and the electrons are the same number

MAN= mass = atomic number - neutrons

121 - 80 = 41

i haven't done this in a while so hope this helps :)
