The property of two isotopes, L and M, which would not be common, is to be predicted. Concept Introduction: The three subatomic particles are electrons, neutrons and protons. Out of these three, neutrons and protons are located inside the nucleus of an atom. In case of a neutral atom, the number of protons is equal to number of electrons. Atomic number of an atom is same as the number of protons. The mass number is calculated as the sum of neutrons and protons in an atom. Isotopes are the atoms which have same atomic number but different mass numbers.

Question

The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…

Question

Chapter 2, Problem 2.83E

Interpretation Introduction

Interpretation:

The property of two isotopes, L and M, which would not be common, is to be predicted.

Concept Introduction:

The three subatomic particles are electrons, neutrons and protons. Out of these three, neutrons and protons are located inside the nucleus of an atom. In case of a neutral atom, the number of protons is equal to number of electrons. Atomic number of an atom is same as the number of protons. The mass number is calculated as the sum of neutrons and protons in an atom. Isotopes are the atoms which have same atomic number but different mass numbers.
