Nomenclature

Concept

100

What is an ion?

An atom that either gains or loses electrons to become charged (+/-).

200

Where do you find transition metals in the periodic table?

Generally in the middle, rectangular area of the periodic table (Group 3-12).

300

How can you tell if an element is a metal or nonmetal?

Generally, elements on the left side of the "staircase" are metals while the ones on the right side are nonmetals.

400

Why do metals tend to form cations?

Because metals tend to donate electrons, causing the atom to be positively charged.

500

Why do transition metals require Roman numerals when naming them?

Because they don't have a constant charge as it can donate different number of electrons.
