If you use opiates for an extended period of time, your body becomes desensitized to the drug. Youâll need more of it to feel its effects. Extended use of opiates changes the structure of nerve cells in your brain. These cells will begin to need the drug just to function properly.
As of 2016, the periodic table has 118 confirmed elements, from element 1 (hydrogen) to 118 (oganesson). Elements 113, 115, 117 and 118 were officially confirmed by the International Union of Pure and Applied Chemistry (IUPAC) in December 2015.
There are 18 groups (columns) in the periodic table. Group 1 (also known as the alkali metals) is the column on the far left of the table. Elements in the same group have similar, but not identical characteristics. This is because they all have the same number of electrons in their outermost shell.
