Block (periodic table) the s-block, with its outer (and only) electrons in the 1s atomic orbital, although its chemical properties are more similar to the p-block noble gases due to its full shell. In addition to the blocks listed in this table, there is a hypothetical g-block which is not pictured here. The g-block elements can be seen in the expanded extended periodic table. Lanthanum and actinium are placed under scandium and yttrium to reflect their status as d-block elements, as they have no electrons in the 4f and 5f orbitals, respectively, while lutetium and lawrencium do. The s-block is on the left
Symbol table A C compiler that parses this code will contain at least the following symbol table entries: In addition, the symbol table will also contain entries generated by the compiler for intermediate expression values (e.g., the expression that casts the codice_1 loop variable into a codice_2, and the return value of the call to function codice_3), statement labels, and so forth. An example of a symbol table can be found in the SysV Application Binary Interface (ABI) specification, which mandates how symbols are to be laid out in a binary file, so that different compilers, linkers and loaders can all consistently
