Question

8 multiple choice 1 point find the symbol for the element with 13 protons and 14 neutrons 25al 14al 13al 27al 9 multiple choice 1 point which type of radiation is made of high energy x - rays? alpha beta gamma 10 multiple choice 1 point which type of radiation is made of 2 protons and 2 neutrons? alpha beta gamma 11 multiple choice 1 point find the product created when silver - 108 undergoes alpha decay. ruthenium - 104 ruthenium - 105 rhodium - 104 rhodium - 105

Explanation:

1. Atomic number = protons. 13 is aluminum, mass number = protons + neutrons = 27.
2. Gamma radiation is high - energy x - rays.
3. Alpha particles have 2 protons and 2 neutrons.
4. Alpha decay reduces mass number by 4 and atomic number by 2. Silver has atomic number 47.

Answer:

1. ²⁷Al
2. gamma
3. alpha
4. rhodium - 104
