List the symbol and atomic number of each element.(a) carbon(b) nitrogen(c) sodium(d) potassium(e) copperarrow_forwardMillikan determined the charge on the electron by studyingthe static charges on oil drops falling in an electricfield (Figure 2.5). A student carried out this experiment usingseveral oil drops for her measurements and calculated thecharges on the drops. She (a) What is the significance of the fact that the droplets carrieddifferent charges? (b) What conclusion can the studentdraw from these data regarding the charge of the electron?(c) What value (and to how many significant figures) shouldshe report for the electronic charge?obtained the following data:arrow_forward

(b) All atoms of the same element have the same number of protons. (m) The three isotopes of hydrogen (hydrogen1, hydrogen2, and hydrogen3) differ only in the number of neutrons in the nucleus. (a) Matter is divided into elements and pure substances. (b) Matter is anything that has mass and volume (occupies space). (c) A mixture is composed of two or more pure substances. (l) The combining ratio of 1:2 in the compound CO2 tells you that this compound is formed by the combination of one gram of carbon with two grams of oxygen.arrow_forward
