Electronegativity Periodic Table. This free periodic table is color-coded to indicate the electronegativity of an atom of an element. Electronegativity is a trend naturally exhibited in the periodic table, but as you can see, it’s not a hard-and-fast trend.

The atomic number is the number of protons inside the nucleus of an atom. It is represented by the symbol Z in equations because Z is the first letter in the word atomic number (definitely not true). Each element can be identified from this number alone. It is always a whole number greater than zero when used to identify an element.

Near-future space science fiction almost by definition has the same shared background of a large human presence in space. Practically no SF stories are about the deep space adventures of an automated space probe, they are mostly about astronauts (with or without the Right Stuff) traveling to other planets and doing things.
