    HI guys i hope you can help me...
    unfortunately i was not in on this day in class and we got some question to answer....and I can not answer this question...i hope some of you can help me...
    this are the question:

    A) Describe, with the aid of diagrams where it would make your description clearer, the basic structure of an atom.

    B) Describe what happens to atoms when they emit alpha (α), beta (ß+ and ß-), and gamma (y) radiation. You will need to say what each type of radiation cosists of and consider the number of protons and neutrons in the atom before and after the emission of radiation. Also, describe the characteristics of each type of radiation.

    I hope so much some of you can help me and can answer this terrible question...THANKS SO MUCH!! BEST WISHES


    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Please try to formulate answers to both question before asking for assistance. The basic structure of atoms is well known. What is the relationship of the atomic electrons and nucleus.

    For the second question, please identify the characteristics of alpha (α), beta (ß+ and ß-), and gamma (y) radiation, and based on that, please identify what one thinks will happen when a nuclear emits such radiation.

    One's textbook should be very clear on these questions.

    Surely you can remember your answer, or if not, you can attempt the question again?

    Then why not attempt the question again? The Forum Guidelines prohibit us from providing Homework Help unless you show that you have attempted the question yourself.
