Concept explainers
(a)
Interpretation:
Complete symbol for chlorine atom with 20 neutrons has to be given.
Concept Introduction:
Each and every element present in the Periodic table has a unique name. Some of the elements are named considering their
Chemical names are represented as atomic symbols. In the symbols, the mass number and atomic number are shown. The complete
Atomic number is the total number of protons present in the atom of an element. Mass number is the total number of protons and neutrons present in nucleus of an atom.
(b)
Interpretation:
Complete symbol for calcium atom with 20 neutrons has to be given.

- During nuclear decay a 238U atom can break apart into a helium-4 atom and one other atom. Assuming that no subatomic particles are destroyed during this decay process, what is the other element produced?arrow_forwardThere are 2.619 1022 atoms in 1.000 g of sodium. Assume that sodium atoms are spheres of radius 1.86 and that they are lined up side by side. How many miles in length is the line of sodium atoms?arrow_forward2.75 Chlorine has only two isotopes, one with mass 35 and the other with mass 37. One is present at roughly 75% abundance, and the atomic weight of chlorine on a periodic table is 35.45. Which must be the correct mass spectrum for chlorine?arrow_forward
- 2.90 Naturally occurring europium has an average atomic weight of 151.964 amu. If the only isotopes of europium present are 151Eu and 153Eu, describe how you would determine the relative abundance of the two isotopes. Include in your description any information that would need to be looked up.arrow_forwardFrom the following written description, write the balanced chemical equation for the reaction including state symbols. A diatomic gaseous molecule that contains 17 protons per atom is reacted with a solid element that has an atomic number of 19 to yield an ionic compound.arrow_forwardA sample of metallic element X, weighing 3.177 g, combines with 0.6015 L of O2 gas (at normal pressure and 20.0C) to form the metal oxide with the formula XO. If the density of O2 gas under these conditions is 1.330 g/L, what is the mass of this oxygen? The atomic weight of oxygen is 15.999 amu. What is the atomic weight of X? What is the identity of X?arrow_forward
- Mass spectrometric analysis showed that there are four isotopes of an unknown element having the following masses and abundances: Three elements in the periodic table that have atomic weights near these values are lanthanum (La), atomic number 57, atomic weight 138.9055; cerium (Ce), atomic number 58, atomic weight 140.115; and praseodymium (Pr), atomic number 59, atomic weight 140.9076. Using the data above, calculate the atomic weight, and identify the element if possible.arrow_forward2.74 The accompanying table provides the identity of the two naturally occurring isotopes for four elements and the atomic weights for those elements. (In each case, the two isotopes differ in mass number by two.) Which element has the mass spectrum shown? Explain your answer.arrow_forwardDefine the term atomic weight. Why might the values of atomic weights on a planet elsewhere in the universe be different from those on earth?arrow_forward
