Chapter 2: Problem 21

Elements whose names end with "-ium" are usually metals; sodium is one example. Identify a nonmetal whose name also ends with "-ium."

Short Answer

Expert verified
Helium is a nonmetal whose name also ends with '-ium.'

Step by step solution

01

Analyzing Element Names

Start by looking at the periodic table and identifying those elements whose names end with '-ium'.
02

Classifying Elements

Next, classify these '-ium' ending elements into metals and nonmetals. Remember that you are looking for a nonmetal.
03

Finding the correct Element

Upon classification and going through the elements systematically, 'Helium' would be identified as a non-metal ending with '-ium'.

Calculate the number of neutrons of \({ }^{239} \mathrm{Pu}\).

Ethane and acetylene are two gaseous hydrocarbons. Chemical analyses show that in one sample of ethane, \(2.65 \mathrm{~g}\) of carbon are combined with \(0.665 \mathrm{~g}\) of hydrogen, and in one sample of acetylene, \(4.56 \mathrm{~g}\) of carbon are combined with \(0.383 \mathrm{~g}\) of hydrogen. (a) Are these results consistent with the law of multiple proportions? (b) Write reasonable molecular formulas for these compounds.

Name these compounds: (a) \(\mathrm{Na}_{2} \mathrm{CrO}_{4},\) (b) \(\mathrm{K}_{2} \mathrm{HPO}_{4}\) (c) HBr (gas), (d) HBr (in water), (e) \(\mathrm{Li}_{2} \mathrm{CO}_{3},\) (f) \(\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7},(\mathrm{~g}) \mathrm{NH}_{4} \mathrm{NO}_{2}\) (h) \(\mathrm{PF}_{3}\) (i) \(\mathrm{PF}_{5},\) (j) \(\mathrm{P}_{4} \mathrm{O}_{6}\) (k) \(\mathrm{CdI}_{2}\) - (I) \(\mathrm{SrSO}_{4},(\mathrm{~m}) \mathrm{Al}(\mathrm{OH})_{3},(\mathrm{n}) \mathrm{Na}_{2} \mathrm{CO}_{3} \cdot 10 \mathrm{H}_{2} \mathrm{O} .\)

Many ionic compounds contain either aluminum (a Group \(3 \mathrm{~A}\) metal) or a metal from Group \(1 \mathrm{~A}\) or Group \(2 \mathrm{~A}\) and a nonmetal - oxygen, nitrogen, or a halogen (Group \(7 \mathrm{~A}\) ). Write the chemical formulas and names of all the binary compounds that can result from such combinations.

Define these terms: (a) \(\alpha\) particle, (b) \(\beta\) particle, (c) \(\gamma\) ray, (d) X ray.
