A face centered cubic cell has an edge length of 495 pm. What is that atomic radius?

Chemistry
1 answer:
Stolb23 [73]3 years ago
5 0

Answer:

r = ¼a√2

Explanation:

For a face centered cubic cell, which we call FCC, the atoms at the face diagonals touch each other.

Now, If we denote the edge length of cube to be "a" and the radius of the atom is denoted as "r", as seen in the attached FCC cell:

(√2)a = 4r

Divide both sides by 4 to get;

r = ¼a√2

Why is helium found in deposits of uranium and thorium vores? What kind of radioactive emission produces it?
Drupady [299]

Two protons and two neutrons are emitted and trapped as materials like uranium and thorium deep underground decay into radium and thorium, respectively. These alpha-particles transform into stable helium atoms as they take on electrons from their surroundings.

<h3>What elements go through alpha decay?</h3>

Alpha decay usually occurs in heavy nuclei such as uranium or plutonium, and therefore is a major part of the radioactive fallout from a nuclear explosion.

<h3>Where does alpha decay occur?</h3>

Alpha decay occurs most often in massive nuclei that have too large a proton to neutron ratio. An alpha particle, with its two protons and two neutrons, is a very stable configuration of particles.
