How to read the periodic table?
1) Read the periodic table from top left to bottom right. The elements are ordered by their atomic numbers, which increase as you move across and down the periodic table. 2) Observe that each element contains 1 more proton than its predecessor. You can tell this by looking at the atomic number. 3) Recognize groups, which share physical and chemical properties. Groups, also known as families, fall in a vertical column. 4) Notice why gaps exist in the table. Although elements are ordered based on their atomic number, they’re also arranged into groups and families that share the same physical and 5) Notice that each row is called a period. All of the elements in a period have the same number of atomic orbitals, which is where their electrons go. 6) Distinguish between metals, semi-metals, and non-metals. You can better understand the properties of an element by recognizing what type of element it is.
How do you memorize the periodic table?
To memorize the periodic table, print a copy of the periodic table and take it with you so you can study on the go. You can also make flashcards for each element by writing the symbol on one side and listing the full name of the element on the other.
What does the periodic table tell us?
– The table can be used to predict the properties of elements, even those that have not yet been discovered. – Columns (groups) and rows (periods) indicate elements that share similar characteristics. – The table makes trends in element properties apparent and easy to understand. – The table provides important information used to balance chemical equations.
How do you find elements in the periodic table?
To find the number of electrons an element has, locate it on the periodic table of elements, find the atomic number, and note the number of protons; because atoms are naturally electrically neutral, the protons and electrons are usually equal. Look at the oxidation number for further information.
