They are both dynamics. P stands for piano, which means quiet, and F means Forte, which means loud.
The symbol for piano is music is a bold italics p which looks very similar to this: p

4: the s-block, the p-block, the d-block, and the f-block. there is an theoratical g-block but its not counted because its theoratical lol.
A horizontal row of blocks in the periodic table is referred to as a period. The sublevels in a period that contain 32 elements are s, p, d and f.
1[+] Helium‎ (5 C, 1 P, 59 F)2[+] Neon‎ (3 C, 1 P, 56 F)3[+] Argon‎ (2 C, 1 P, 25 F)4[+] Krypton‎ (2 C, 1 P, 18 F)5[+] Xenon‎ (2 C, 1 P, 19 F)6[×] Radon‎ (1 P, 18 F)7[×] Ununoctium‎ (1 P, 9 F)
s,p,d,f block elements metals, non-metals and metalloids
The s, p, d, f block realte to the filling of the outer shell orbitals. Group 1 and 2 are the s block. Groups 13-18 the p block, the transition metals the d block and the lanthanides and actinides the f block.
P-F is Polar
•Soluble or incompatible elements are dissolved •B, F, P, S, Cu
The group 17 of p block has 7 valent electrons. These elements are called halogens.
Elements can be categorized into 4 differents blocks, s block, d block, p block and f block.
