CHEMISTRY HOLIDAY HOMEWORK PROJECT Periodic Table & Electronic Configuration of s-Block and p-Block Elements Name: ____________________ Class: ____________________ Roll No.: ____________________ School: ____________________ Introduction The Modern Periodic Table arranges elements according to their atomic numbers. Elements with similar properties are placed in the same group. The table contains 18 groups and 7 periods. Draw a neat periodic table in your notebook and label s-block, p-block, d-block and f-block. Electronic Configuration of s-Block Elements Element Atomic No. Electronic Configuration Li 3 1s² 2s¹ Be 4 1s² 2s² Na 11 1s² 2s² 2pn 3s¹ Mg 12 1s² 2s² 2pn 3s² K 19 1s² 2s² 2pn 3s² 3pn 4s¹ Ca 20 1s² 2s² 2pn 3s² 3pn 4s² General Electronic Configuration: ns¹ – ns² Element | Atomic No. | Electronic Configuration Li | 3 | 1s² 2s¹ Be | 4 | 1s² 2s² Na | 11 | 1s² 2s² 2pn 3s¹ Mg | 12 | 1s² 2s² 2pn 3s² K | 19 | 1s² 2s² 2pn 3s² 3pn 4s¹ Ca | 20 | 1s² 2s² 2pn 3s² 3pn 4s² Electronic Configuration of p-Block Elements Element Electronic Configuration B 1s² 2s² 2p¹ C 1s² 2s² 2p² N 1s² 2s² 2p³ O 1s² 2s² 2pn F 1s² 2s² 2pn Ne 1s² 2s² 2pn Al [Ne] 3s² 3p¹ Si [Ne] 3s² 3p² P [Ne] 3s² 3p³ S [Ne] 3s² 3pn Cl [Ne] 3s² 3pn Ar [Ne] 3s² 3pn General Electronic Configuration: ns² np¹ – ns² npn Element | Electronic Configuration B | 1s² 2s² 2p¹ C | 1s² 2s² 2p² N | 1s² 2s² 2p³ O | 1s² 2s² 2pn F | 1s² 2s² 2pn Ne | 1s² 2s² 2pn Al | [Ne] 3s² 3p¹ Si | [Ne] 3s² 3p² P | [Ne] 3s² 3p³ S | [Ne] 3s² 3pn Cl | [Ne]
I have some experience reviewing and categorizing data for learning purposes. I have worked on tasks such as labeling images, organizing information, and checking text for accuracy. While my experience is not professional, it has helped me develop attention to detail and an understanding of how AI training data is prepared and evaluated.
