Which element has the electronic configuration 1s2 2s2 2p6 3s2 3p1?
Step 1: Understand that the electronic configuration describes how electrons are arranged in an atom.
Step 2: Break down the electronic configuration: 1s2 means there are 2 electrons in the 1s orbital, 2s2 means 2 electrons in the 2s orbital, 2p6 means 6 electrons in the 2p orbital, 3s2 means 2 electrons in the 3s orbital, and 3p1 means 1 electron in the 3p orbital.
Step 3: Count the total number of electrons: 2 (1s) + 2 (2s) + 6 (2p) + 2 (3s) + 1 (3p) = 13 electrons.
Step 4: Identify the element with 13 electrons on the periodic table. This element is Aluminum (Al).
