Passage IV
Figure 1 is a simplified periodic table giving the name, symbol, and atomic number (number of protons in the nucleus) for 20 elements. The elements in a column belong to a group. The elements in a row belong to a period.
Table 1 gives the melting point at 1 atmosphere (atm) of pressure (the MP), the boiling point at 1 atm (the BP), and the atomic radius for one or more of the elements in each group. The atomic radius, in picometers (pm; 1 pm = 10-12 m), is a measure of the size of an atom. Table 1 also lists an ion for each element and the ionic radius of that ion (a measure of its size).
22. Based on Table 1, at 1,000°C and 1 atm, aluminum exists in what state and sodium exists in what state?
Your Answer is
Correct Answer is H
Explanation
According to table 1, Aluminum's MP is 660, BP is 2470, it should be liquid at 1000°C;
Sodium's MP is 98, BP is 890, so it should be at 1000°C is gaseous
