How can you memorize periodic table charges?

Question

Natalie Anton · Accepted Answer

Know the families on the Periodic Table, the elements with multiple charges (only the major ones - used more often), and the exceptional elements with 0 charge.

Recognize the Periodic Table's elemental families. For instance, alkali metals, which all have a 1+ charge, and noble gases, which are all stable and have no charge, will not react in normal conditions. You can follow the trend and ascertain the charge of each element (in that family) by knowing the family to which it belongs and the elements it consists of. If an element has several charges, identify its major ones (minor ones are rarely tested). Major elements include chromium, iron, copper, tin, gold, and/or mercury. The most significant elements are likely iron and copper (and possibly gold). Other than the Noble Gases, some elements have no charge at all, such as silicon, carbon, and boron; since they are non-metals, they will share electrons. On assessments, teachers typically use common elements; ferromagnets or neodymium are extremely uncommon. Furthermore, because it is unreasonable for a student to not possess a Periodic Table, most assessors also give them out. That being said, assessors may test students on specific or fundamental chemistry knowledge. I hope this is helpful.

undefined Understanding the common oxidation states of elements based on their group number and position in the periodic table will help you memorize periodic table charges; you can also help reinforce this knowledge by practicing and reviewing frequently.
