12. How can you describe the location of Gold (Au, Atomic Number 79) on the periodic table . Choose two options *
A. Matalloid
B. Group 11, Period 6
C. Group 6, Period 11
D. Metal
I think the answer is a
Answer: b and d
Gold is located in the 11th group (numbers on the top of the p table) on the periodic table, and in the 6th row (numbers on the side). It is part of the transition metals section (the block in the middle) and so is a metal.
a won't do it
To describe the location of Gold (Au, Atomic Number 79) on the periodic table, we need to understand its atomic number, which determines its position. Here's how you can find the answer:
Step 1: Look for the atomic number of Gold (79).
Step 2: Locate the row (period) corresponding to the atomic number.
Step 3: Identify the column (group) in which it is placed.
In this case, the correct options to choose from are:
A. Metalloid - Metalloids are elements that exhibit some properties of metals and some of non-metals. Gold is not a metalloid, so we can eliminate this option.
B. Group 11, Period 6 - This option describes the location of Gold accurately. Gold belongs to Group 11, which is also known as the Coinage Metals group. It is located in Period 6, which refers to the row in which it is placed. Therefore, this option is correct.
C. Group 6, Period 11 - This option does not exist on the periodic table because there are only 7 periods. Periods are numbered from 1 to 7, so we can eliminate this option.
D. Metal - Gold is indeed a metal, so this option is correct. However, if you had to choose two options, B (Group 11, Period 6) would be a more specific and accurate description of its location.
