Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of _______ and ______. (cal
WARRIOR [948]

Answer:

Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.

Explanation:

Nuclear Fusion is the Nuclear process in which the energy is produced when two lighter elements are collided together which are having some kinetic energy in them after that the two lighter nuclei will fuse together into a single heavier nuclei. This is opposite to what happens in Fission process in which the breaking up of atomic specie happens.

Both Nuclear Fission and Nuclear fission occurs with the release of massive amount of energy.

There are conditions for nuclear fusion to happens like, it requires 100 million's kelvin of temperature, also fusion will occur when the pressure is very high because increased pressure will result into squeezing of the atomic specie and hence they will fuse.

When the Hydrogen atom fuse together to form helium atoms. This release a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.

If L = 5, then the magnetic quantum number "mL" can be equal to
Anit [1.1K]

b. -5, -4, -3, -2, -1, 0, +1, +2, +3, +4, +5

<h3>Further explanation</h3>

Each orbital in an atom consists of 4 quantum numbers  

n is the principal quantum number.  

l is the angular momentum / azimuthal quantum number  

ml, the magnetic quantum number  

ms, the electron-spin quantum number  

Value of n: positive integer  

value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)

ml value: between -l to + l  

ms value: +1/2 or -1/2  

So for L=5, mL value : -5 to +5

What would probably happen if it took the Earth longer to orbit the Sun than it does now? *
Setler79 [48]

B

the Earth is eccentric,this means that it has changed repeatedly over time

And if it took the earth more time to orbit round the sun than it does now the years would have more than Han 365 days a year
