Transcript text: Write the symbol for every chemical element that has atomic number greater than 32 and atomic mass less than 84.3 u .

Solution

Step 1: Identify the Range of Atomic Numbers

We need to find elements with atomic numbers greater than 32. This means we start from atomic number 33 and go upwards.

Step 2: Identify the Range of Atomic Masses

We are looking for elements with atomic masses less than 84.3 u.

Step 3: List Elements within the Specified Atomic Number Range

The elements with atomic numbers greater than 32 are:

Step 4: Filter Elements by Atomic Mass

Now, we filter the above list to include only those elements with atomic masses less than 84.3 u:

\[ \boxed{\text{As, Se, Br, Kr}} \]
