S -P -D - F Orbital Blocks on Periodic Table

Summary

In this video, Mumu Math and Science explores the different orbital blocks on the periodic table. The S, P, D, and F blocks are explained in terms of where the last electron enters for each element. Viewers learn about the characteristics of elements in each block, such as the reactivity and softness of S-block metals, the non-metals in the P-block, and the high melting points of transition metals in the D-block. The F-block, containing the inner transition elements, is also discussed. The video ends with a reminder that kindness multiplies kindness, encouraging viewers to be kind to someone today.

Takeaways

• 😀 The periodic table is divided into different blocks: S, P, D, and F blocks.
• 😀 The S block is on the left side of the periodic table, except for hydrogen.
• 😀 The P block is on the right side of the periodic table.
• 😀 The D block is in the middle, containing the transition metals.
• 😀 The F block is located below the transition metals and contains inner transition elements.
• 😀 The placement of elements in these blocks is determined by the electron configuration and the orbital in which the last electron is found.
• 😀 Elements in the S block have their last electrons in the S orbital.
• 😀 Elements in the D block have their last electrons in the D orbital.
• 😀 The names of orbitals (S, P, D, F) come from spectroscopic terms: Sharp, Principal, Diffused, and Fundamental.
• 😀 There is no G block in the periodic table, as no elements have been observed in this orbital, though 'G' was chosen for alphabetical reasons.
• 😀 Elements in the same block share similar properties due to their similar electron configurations and orbital characteristics.

Q & A

What are the different orbital blocks on the periodic table?

The periodic table has four orbital blocks: the S block on the left, the P block on the right, the D block in the middle, and the F block below the transition metals.

How are the blocks on the periodic table determined?

The blocks are determined by which orbital the last electron of an element enters. For example, elements in the S block have their last electrons in the S orbital.

What does the electron configuration of S block elements look like?

For S block elements, the last electrons are in the S orbital. This characteristic defines the placement of these elements in the S block.

Why are orbitals named S, P, D, and F?

The orbitals are named based on the spectroscopic lines of atomic spectra. 'S' stands for 'sharp', 'P' stands for 'principal', 'D' stands for 'diffused', and 'F' stands for 'fundamental'.

Are there any elements in the G block?

No, there are no G block elements observed so far. The letter 'G' was chosen because it comes after 'F' in the alphabetical order, even though no such elements have been discovered yet.

What types of elements are found in the S block?

The S block contains metals that are generally reactive, soft, and have low melting points.

What kinds of elements are found in the P block?

The P block contains non-metals and elements that typically form covalent bonds.

What are the characteristics of D block elements?

D block elements, also known as transition metals, have high melting and boiling points.

What is unique about the F block elements?

The F block contains inner transition metals, which are metals with high melting points.

How do elements in the same block of the periodic table relate to each other?

Elements in the same block have similar properties because they have valence electrons in the same type of orbital.
