k-40 1.01%
k-41 6.73%
2. Calculate the atomic mass of X given the precise atomic masses and the percent abundance of each isotope of the element x below
x-13 12.98504 78.70%
x-15 14.98584 10.13%
3. You are given the following symbol 231Ra
What is the Atomuc number
What is the Atomic Mass?
What is the number of P+
What is the number of N
What is the number of e
What is the Charge
4. You are given the following symbol 212Po
What is the Atomuc number
What is the Atomic Mass?
What is the number of P+
What is the number of N
What is the number of e
What is the Charge
Explanation / Answer
1) 39.18 amu
2) 13.5 amu
3) symbol 231Ra
the Atomuc number = 88
the Atomuc mass = 231 u
number of P+ = 88
number of N = 143
number of e = 88
the Charge = 0
4) symbol 212Po
the Atomuc number = 84
the Atomuc mass = 211 u
number of P+ = 84
number of N = 128
number of e = 84
the Charge = 0
