Positive and Negative Ions: ions and Anions - …

2019-4-22 · ions (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride. A metal reacts with a nonmetal to form an ionic bond.

Scandium - Element information, properties and uses

In 1869, Mendeleev noticed that there was a gap in atomic weights between calcium (40) and titanium (48) and predicted there was an undiscovered element of intermediate atomic weight. He forecast that its oxide would be X 2 O 3. It was discovered as scandium in 1879, by Lars Frederik Nilson of the University of Uppsala, Sweden.

Ionic radius - The Full Wiki

Ionic Radius, r ion, is a measure of the size of an ion in a crystal lattice.It is measured in either picometres (pm) or Angstrom (Å), with 1 Å = 100 pm. Typical values range from 30 pm (0.3 Å) to over 200 pm (2 Å). The concept of ionic radius was developed independently by Victor Goldschmidt and Pauling in the 1920s to summarize the data being generated by the (at the time) new technique
