Question

A chemical lab isolates a metallic element from a compound. Tests of

Answer 1

The isolated metallic element that has 4 electrons in its outer shell will most likely be found in group 14.

Periodic Table of elements

The periodic table of elements is a table which arranges elements based on their electronic configurations.

• Elements with the same number of valence electrons are arranged into the same group
• Elements with the same number of electron shells are arranged in periods.

• Elements in group 14 have four valence electrons
• Elements in group 2 have two valence electrons
• Elements in group 15 have five valence electrons
• Elements in group 3 have three valence electrons.

Therefore, the isolated metallic element that has 4 electrons in its outer shell will most likely be found in group 14.
