Chapter 2: Problem 69

What is the symbol for an ion with 63 protons, 60 electrons, and 88 neutrons? If an ion contains 50 protons, 68 neutrons, and 48 electrons, what is its symbol?

Short Answer

Expert verified
The symbols for the ions are \(\mathrm{^{151}Eu^{3+}}\) for the ion with 63 protons, 60 electrons, and 88 neutrons, and \(\mathrm{^{118}Sn^{2+}}\) for the ion with 50 protons, 68 neutrons, and 48 electrons.

Step by step solution

01

Identify the element

Based on the number of protons (63), we can identify the element. In this case, 63 protons correspond to the element Europium (Eu).
02

Calculate the charge of the ion

To determine the charge of the ion, we need to find the difference between the number of protons and electrons. In this case, the ion has 63 protons and 60 electrons, which results in a charge of +3 (since there are 3 more protons than electrons).
03

Determine the mass number

The mass number is the sum of protons and neutrons. In this case, there are 63 protons and 88 neutrons, which results in a mass number of 151.
04

Write the ion symbol

To write the ion symbol, use the element symbol (Eu), the mass number (151), and the charge (+3). The ion symbol is: \(\mathrm{^{151}Eu^{3+}}\). Question 2 - Ion with 50 protons, 68 neutrons, and 48 electrons.
05

Identify the element

Based on the number of protons (50), we can identify the element. In this case, 50 protons correspond to the element Tin (Sn).
06

Calculate the charge of the ion

To determine the charge of the ion, we need to find the difference between the number of protons and electrons. In this case, the ion has 50 protons and 48 electrons, which results in a charge of +2 (since there are 2 more protons than electrons).
07

Determine the mass number

The mass number is the sum of protons and neutrons. In this case, there are 50 protons and 68 neutrons, which results in a mass number of 118.
08

Write the ion symbol

To write the ion symbol, use the element symbol (Sn), the mass number (118), and the charge (+2). The ion symbol is: \(\mathrm{^{118}Sn^{2+}}\).

Two elements, R and Q, combine to form two binary compounds. In the first compound, 14.0 g of R combines with 3.00 g of Q. In the second compound, 7.00 g of R combines with 4.50 g of Q. Show that these data are in accord with the law of multiple proportions. If the formula of the second compound is RQ, what is the formula of the first compound?

The designations 1A through 8A used for certain families of the periodic table are helpful for predicting the charges on ions in binary ionic compounds. In these compounds, the metals generally take on a positive charge equal to the family number, while the nonmetals take on a negative charge equal to the family number minus eight. Thus the compound between sodium and chlorine contains \(\mathrm{Na}^{+}\) ions and \(\mathrm{Cl}^{-}\) ions and has the formula NaCl. Predict the formula and the name of the binary compound formed from the following pairs of elements. a. Ca and N b. \(\mathrm{K}\) and \(\mathrm{O}\) c. \(\mathrm{Rb}\) and \(\mathrm{F}\) d. Mg and S e. Ba and I f. Al and Se g. \(\mathrm{Cs}\) and \(\mathrm{P}\) h. In and Br

Each of the following compounds has three possible names listed for it. For each compound, what is the correct name and why aren鈥檛 the other names used? a. \(\mathrm{N}_{2} \mathrm{O} :\) nitrogen oxide, nitrogen(1) oxide, dinitrogen monoxide b. \(\mathrm{Cu}_{2} \mathrm{O}\) : copper oxide, copper(1) oxide, dicopper monoxide c. \(\mathrm{Li}_{2} \mathrm{O}\) : lithium oxide, lithium(1) oxide, dilithium monoxide

The two most reactive families of elements are the halogens and the alkali metals. How do they differ in their reactivities?

Give the names of the metals that correspond to the following symbols: Sn, Pt, Hg, Mg, K, Ag.
