    E) all are the same

    Explanation:

    The question requires we identify the amount of an element with the greatest number of particles.

    We need to know that 1 mole of an element contains particles equivalent to the Avogadro's number, 6.022 * 10^23. That is, 1 mole of an element = 6.022 * 10^23 particles

    In this case;

    Choice A

    1 mole of Na

    1 mole of Na contains 6.022 * 10^23 atoms

    Choice B

    22.990 g of Na

    The molar mass of sodium is 22.99 g/mol

    Therefore, 22.990 g of Na contains 6.022 * 10^23 atoms

    Choice C

    1 mole of Be

    1 mole of Be contains 6.022 * 10^23 atoms

    Choice D

    9.012 g of Be

    But, the molar mass of Be is 9.012 g

    Thus; 9.012 g of Be contains 6.022 * 10^23 atoms

    We can therefore, conclude that all the given choices are the same, they have equal number of particles.
