A Bohr model of Argon will have how many atoms at each level? 1st level: 2
2nd level: 8
3rd level: 8

1st level: 8
2nd level: 8
3rd level: 8
1st level: 2
2nd level: 10
3rd level: 6

There’s 18 protons and 22 neutrons but what does it mean by levels

Explanation:

you gotta add the following molecules so we can give u an answer

explanation:

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
