Chapter 8: Problem 91

State whether each of the elements listed here is a gas, a liquid, or a solid under atmospheric conditions. Also state whether it exists in the elemental form as atoms, as molecules, or as a three-dimensional network: \(\mathrm{Mg}, \mathrm{Cl}, \mathrm{Si}, \mathrm{Kr}, \mathrm{O}, \mathrm{I}\) \(\mathrm{Hg}, \mathrm{Br}\).

Short Answer

Expert verified
\(\mathrm{Mg}\) is a solid and exists as atoms. \(\mathrm{Cl}\) is a gas and exists as molecules. \(\mathrm{Si}\) is solid and exists as a three-dimensional network. \(\mathrm{Kr}\) is a gas and exists as atoms. \(\mathrm{O}\) is a gas and exists as molecules. \(\mathrm{I}\) is a solid and exists as molecules. \(\mathrm{Hg}\) is a liquid and exists as atoms. \(\mathrm{Br}\) is a liquid and exists as molecules.

Step by step solution

01

Determine the state of matter

Find the states of the given elements under atmospheric conditions. This information is generally found in the periodic table. Here are the results: \(\mathrm{Mg}\) is a solid, \(\mathrm{Cl}\) is a gas, \(\mathrm{Si}\) is a solid, \(\mathrm{Kr}\) is a gas, \(\mathrm{O}\) is a gas, \(\mathrm{I}\) is a solid, \(\mathrm{Hg}\) is a liquid, and \(\mathrm{Br}\) is a liquid.
02

Determine the elemental form

Identify whether the listed elements exist as atoms, molecules or as a three-dimensional network: \(\mathrm{Mg}\) exists as atoms, \(\mathrm{Cl}\) exists as molecules, \(\mathrm{Si}\) exists as a three-dimensional network, \(\mathrm{Kr}\) exists as atoms, \(\mathrm{O}\) exists as molecules, \(\mathrm{I}\) exists as molecules, \(\mathrm{Hg}\) exists as atoms, and \(\mathrm{Br}\) exists as molecules.

Write the outer electron contigurations for (a) the alkali metals, (b) the alkaline earth metals, (c) the halogens, (d) the noble gases.

A student is given samples of three elements, \(X, Y\) and \(Z\), which could be an alkali metal, a member of Group \(4 \mathrm{~A},\) and a member of Group \(5 \mathrm{~A}\). She makes the following observations: Element X has a metallic luster and conducts electricity. It reacts slowly with hydrochloric acid to produce hydrogen gas. Element \(Y\) is a light-yellow solid that does not conduct electricity. Element \(Z\) has a metallic luster and conducts electricity. When exposed to air, it slowly forms a white powder. A solution of the white powder in water is basic. What can you conclude about the elements from these observations?

The \(\mathrm{H}^{-}\) ion and the He atom have two \(1 \mathrm{~s}\) electrons each. Which of the two species is larger? Explain.

Which elements are more likely to form acidic oxides? basic oxides? amphoteric oxides?

Explain which of these ions is larger, and why: \(\mathrm{Cu}^{+}\) or \(\mathrm{Cu}^{2+}\).
