Concept explainers
Interpretation:
The chemical formulas for the elements that normally exist in nature as diatomic molecules are to be determined.
Concept Information:
The substances that are unable to be degraded into simpler substances are known as an element.
The molecules which contain single atoms are called monatomic molecules and those contain two different atoms are called diatomic molecules.
The element symbols and the subscripts in an ionic compound are represented with the help of a chemical formula.
While writing the chemical formula for an ionic compound, the symbol of the metal is written first which is then followed by the symbol of the non-metal.
Electrical neutrality is maintained in all the chemical compounds. Due to this, the ions that are present in an ionic compound have a fixed ration in such a way that the positive charge is equal to the negative charge.

Chemistry: The Molecular Nature of Matter
- Give some examples of inorganic compounds?arrow_forwardA compound contains 43.84 % carbon atoms, 3.65 % hydrogen atoms, and 8.68 % fluorine atoms by mass. Each molecule of this compound contains one fluorine atom. What is the total number of carbon, hydrogen, and fluorine atoms in one molecule of this compound?arrow_forwardWrite the symbols and charges of the monatomic ions formed by calcium AND phosphorus, and write the formula of the compound these ions would make together.arrow_forward
- ings ools Molecular compounds are usually composed solely of nonmetals. A binary molecular compound is one in which the compound contains only two elements (regardless of how many atoms are present of each). When naming binary molecular compounds, prefixes are used to specify the number of atoms of each element. Take a moment to review some of the prefixes shown here. Prefix Number mono di nona one three tetra four penta five hexa six hepta seven octa eight nine deca two ten For example, SF6 is named sulfur hexafluoride. Note that the prefix mono is not used in naming the first element. Also note that the second element in the name should end with the suffix ide. ▼ Part A Using the rules for naming molecular compounds described in the introduction, what is the name for the compound PC15? Spell out the full name of the compound. ►View Available Hint(s) Submit Part B Using the rules for naming molecular compounds described in the introduction, what is the name for the compound N₂ CL?…arrow_forwardWhen water boils, you can see bubbles rising to the surface of the water. Of what arc these bubbles made? air hydrogen and oxygen gas oxygen gas water vapor carbon dioxide gasarrow_forwardContrast the two general types of chemical compounds in terms of their general physical properties.arrow_forward
- You may have noticed that when water boils, you can see bubbles that rise to the surface of the water. Which of the following is inside these bubbles? Explain. a. air b. hydrogen and oxygen gas c. oxygen gas d. water vapor e. carbon dioxide gasarrow_forwardCopper atoms. (a) What is the average mass of one copper atom? (b) Students in a college computer science class once sued the college because they were asked to calculate the cost of one atom and could not do it. But you are in a chemistry course, and you can do this. (See E. Felsenthal, Wall Street Journal, May 9, 1995.) If the cost of 2.0-mm diameter copper wire (99.9995% pure] is currently 41.70 for 7.0 g, what is the cost of one copper atom?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
- Consider the following data for three binary compounds of hydrogen and nitrogen: %H (by Mass) %N (by Mass) I 17.75 82.25 II 12.58 87.42 III 2.34 97.66 When 1.00 L of each gaseous compound is decomposed to its elements, the following volumes of H2(g) and N2(g) are obtained: H2(L) N2(L) I 1.50 0.50 II 2.00 1.00 III 0.50 1.50 Use these data to determine the molecular formulas of compounds I, II, and III and to determine the relative values for the atomic masses of hydrogen and nitrogen.arrow_forwardSketch a magnified view (showing atoms/molecules) of each of the following and explain: a. a heterogeneous mixture of two different compounds b. a homogeneous mixture of an element and a compoundarrow_forwardIndicate whether each of the following statements is true or false. If a statement is false, change it to make it true. (Such a rewriting should involve more than merely converting the statement to the negative of itself.) a. The atom is the limit of chemical subdivision for both elements and compounds. b. Triatomic molecules must contain at least two kinds of atoms. c. A molecule of a compound must be heteroatomic. d. Only heteroatomic molecules may contain three or more atoms.arrow_forward
