so I am working on this question for chemestry and can't figure out the format it wants since I am blind. The question states Write the identity of the missing particle for the following nuclear decay reaction: 4925Mn→4924Cr+? Express your answer as a particle. and my answer is currently 24 Cr49 + e+24 Cr49 + e+. O also I can't read mathmatical graphics/equation editor since majority of those aren't accessible for blind students so could you explain this in just html text? Thanks in advanced

Explanation:

lets take the particle is X, the given decay reaction can be written as follows

Now by using mass balancing:

The sum of the mass of right hand side=The sum of the mass of left hand side

49=49+M

M=0

Now by using atomic number balancing:

Atomic number on right side=Atomic number on left side

25 = 24 + Z

Z=1

Therefore we can say that , the mass of that unknown particle is 0 unit and atomic number is 1.

Thus that particle will be positron.

i need mutiple choices

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
