Question 2:

Currently, 94 different elements are known to exist in nature, although additional elements have been formed in the laboratory.

Question 3:

There are only 94 naturally occurring elements, but there are 118 different elements total.

• For natural occurrence: Most sources confirm that 94 elements occur naturally (some are rare or radioactive, but still natural).
• For total elements: The periodic table has 118 confirmed elements, with the rest (118 − 94 = 24) synthesized in labs.
• The "formed in the ____" blank refers to human-made (synthetic) elements, typically created in laboratories.

Final Answers (Filling the Blanks):

1. Currently, $\boldsymbol{94}$ different elements are known to exist in nature, although additional elements have been formed in the $\boldsymbol{\text{laboratory}}$.
