a.
To determine:
The number of protons and electrons in the chloride ion.
Introduction:
A neutral atom consists of the same number of protons and electrons. This corresponds to the atomic number of an element. If positively charged ion is given then, it has more number of protons than electrons whereas if negatively charged ion is given then, it has more number of electrons than protons.
b.
To determine:
The number of protons and electrons in
Introduction:
Atomic number is the total number of protons or electrons present in an atom.
A neutral atom consists of the same number of protons and electrons. This corresponds to the atomic number of an element. If positively charged ion is given then, it has more number of protons than electrons whereas if negatively charged ion is given then, it has more number of electrons than protons.

- A cube of sodium has length 1.25 in. How many atoms are in that cube? (Note: dNa=0.968g/cm3.)arrow_forwardA gaseous binary compound has a vapor density that is 2.53 times that of nitrogen at 100°C and atmospheric pressure. When 8.21 g of the gas reacts with AlCl3 at 100°C, 1.62 g gaseous nitrogen is produced, removing all of the nitrogen originally present. (a) Estimate the molecular mass of the gaseous compound. (b) How many nitrogen atoms are there in a molecule of the compound? (c) What is the maximum possible value of the atomic mass of the second element? (d) Are other values possible for the atomic mass of the second element? Use a table of atomic masses to identify the element that best fits the data. (e) What is the molecular formula of the compound?arrow_forwardIs it possible for the same Iwo elements to form more than one compound? Is this consistent with Dalton’s atomic theory? Give an example.arrow_forward
- When we refer to doughnuts or cookies, we often refer to 1doz of them, which corresponds to 12. Why is the dozen an inconvenient number when referring to atoms? Why is Avogadros number, 6.0221023, more convenient?arrow_forwardAverage atomic masses listed by JUPAC are based on a study of experimental results. Bromine has two isotopes 79Br and 81Br, whose masses (78.9 183 and 80.9 163 amu) and abundances (50.69% and 49.3 1%) were determined in earlier experiments. Calculate the average atomic mass of bromine based on these experiments.arrow_forwardThese questions concern the work of J. J. Thomson: From Thomson’s work, which particles do you think he would feel are most important in the formation of compounds (chemical changes) and why? Of the remaining two subatomic particles, which do you place second in importance for forming compounds and why? Come up with three models that explain Thomson’s findings and evaluate them. To be complete you should include Thomson’s findings.arrow_forward
- List some properties of a substance that would lead you to believe it consists of ions. How do these properties differ from those of nonionic compounds?arrow_forwardThe element silver (Ag) has two naturally occurring isotopes: 109 Ag and 107Ag with a mass of 106.905 u. Silver consists of 51.82% 107Ag and has an average atomic mass of 107.868 u. Calculate the mass of 109Ag.arrow_forwardThe element europium exists in nature as two isotopes: 151Eu has a mass of 150.9196 u and 153Eu has a mass of 152.9209 u. The average atomic mass of europium is 151.96 u. Calculate the relative abundance of the two europium isotopes.arrow_forward
