Question

1. ccc patterns what patterns do you observe in the electron configurations? 2. cccc patterns use the patterns you identified to complete the table. add the missing electron configurations. 3. sep analyze data use the patterns you identified and the completed table to infer the three rules that describe the order in which the atomic orbitals are filled. 4. sep analyze data find the first column, or group 1, of the periodic table, and then identify the elements included in the table that are organized in this column. what do the electron configurations of these elements have in common?

Explanation:

Step1: Analyze electron - config patterns

Observe trends in known electron configurations, like energy - level filling and orbital order.

Step2: Complete table

Use Aufbau principle (fill lower - energy orbitals first), Pauli exclusion principle (each orbital holds 2 electrons with opposite spins), and Hund's rule (electrons occupy degenerate orbitals singly before pairing) to fill missing configurations.

Step3: Infer filling rules

The three rules are Aufbau principle, Pauli exclusion principle, and Hund's rule.

Step4: Analyze Group 1 elements

Elements in Group 1 have 1 valence electron in an s - orbital of the outermost energy level.

Answer:

1. Patterns include sequential filling of energy levels and orbitals following specific rules.
2. Completed table using electron - filling rules.
3. Rules are Aufbau principle, Pauli exclusion principle, and Hund's rule.
4. Group 1 elements have 1 valence s - electron in outermost energy level.
