Block level elements can be centered by: The margin-left and margin-right properties can be set to some explicit value: body{ width: 40em; background: fluorescent; } p{ width:30 em; margin-right:auto; margin-left:auto } In this case, the left and right margins will be each, five ems wide since they split up the ten ems left over from (40em-30em). It was unnecessary for setting up an explicit width for the BODY element; it was done here for simplicity.

What are the different blocks on the periodic table and how do they contribute to the organization of elements?

The periodic table is divided into four main blocks: s-block, p-block, d-block, and f-block. These blocks help organize elements based on their electron configurations and properties. The s-block elements are found in groups 1 and 2, the p-block elements are in groups 13-18, the d-block elements are in groups 3-12, and the f-block elements are the lanthanides and actinides. Each block represents a different type of electron orbital and helps to group elements with similar chemical properties together.


S block elements densities?

The densities of s-block elements vary depending on the specific element. Generally, s-block elements like lithium, sodium, and potassium have low densities compared to d-block and f-block elements. As you move down the s-block of the periodic table, the densities of the elements tend to increase due to the increase in atomic size and mass.


What elements belong to the p block?
