Question

1. base your answer(s) to the following question(s)

on the information below.
the table below lists physical and
chemical properties of six elements at
standard pressure that correspond to known
elements on the periodic table. the
elements are identified by the code letters, d,
e, g, j, l, and q.

identify, by code letter, the element that is a noble
gas in the \properties of six elements at standard
pressure\ table.

Explanation:

Step1: Recall noble gas properties

Noble gases are chemically inert and do not form oxides under normal conditions.

Step2: Check oxide formula

Looking at the table, Element D has an oxide formula of (none).

Answer:

Element D
