A fluoride ion and neon atom are shown. Which of the following comparisons is true?

• The fluoride ion has a different electron configuration than the neon atom because of the 1- negative charge.

• They are similar because fluorine atom with a single negative charge has the same number of electrons as neon atom with a single negative charge.

• They have the same number of electrons and protons because the nucleus of a fluoride ion is the same as the nucleus of a neon atom and both have 10 protons.

• They have the same number of electrons but different number of protons because, the fluoride ion has 9 protons and 10 electrons, while the neon atom has 10 protons and 10 electrons.

Using the data on the periodic table provided, which of the following statements is TRUE?

• The number of valence electrons increase going from left to right because more electrons are added on the outermost energy level.

• All of the transition metals are solids because they have more in common with metals than they do with nonmetals.

• The noble gases are found on the right side of the periodic table because that is where the nonmetals are found.

• All metals form negative ions because they give up electrons to form bonds in compounds.

The chart shows ion charges for main group elements. How could the elements sulfur (S), neon (Ne), and magnesium (Mg) be organized in order of increasing number of valence electrons?

• neon, sulfur, magnesium

• sulfur, neon, magnesium

• magnesium, sulfur, neon

• magnesium, neon, sulfur

Throughout centuries, the metals copper (Cu), silver (Ag), and gold (Au) have been used to make coins and jewelry because they are less reactive with water, which makes them resistant to corrosion. They are also shiny and have remarkable colors. Which of the following explains how the similar properties of these three metals are reflected in the Periodic Table? (19036)

• They all belong to the same group.

• They all belong to the same period.

• Copper is in group 4; silver is in group 5; and gold is in group 6.

• Copper is in period 4; silver is in period 5; and gold is in period 6.

The periodic table shows the location of all the elements. Which element has chemical properties that are the most similar to chlorine (Cl), and why?

• Sulfur (S), because it is in the same period as chlorine

• Bromine (Br), because it is in the same group as chlorine

• Sodium (Na), because it can combine with chlorine easily

• Selenium (Se), because it belongs to the nonmetals like chlorine

Which of the following elements is a metalloid that would create a positive ion? (4261)

• Aluminum

• Antimony

• Calcium

• Sulfur
