Bromine is the 64th most abundant element in the Earths crust with an abundance of 2.4 mg/kg. The tag in HTML document is used to create a line break in a text. The title also has an additional meaning when taking into account the actual Breaking Bad logo - 'Br Ba.' The design highlights two elements on the Periodic table, 'Br' and 'Ba.
So the electron configuration of bromine will be 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 5. Bromine is the tenth most abundant element in sea water with an abundance of 67.3 mg/L. If the a element has an href attribute, then it represents a hyperlink (a hypertext anchor).
We know that each s subshell can hold maximum 2 electrons, each p subshell can hold maximum 6 electrons, each d subshell can hold maximum 10 electrons, and each f subshell can hold maximum 14 electrons.Īlso, we have to make sure that the electron configuration will match the order of aufbau principle (i.e., the 1s subshell is filled first and then 2s, 2p, 3s… and so on). Both are correct, and both will be accepted by web browsers. Its really kind of a hack where the / is interpreted as an attribute with no value and ignored.
The 1 st electron shell contains 1s subshell, the 2 nd electron shell contains 2s and 2p subshells, the 3 rd electron shell contains 3s, 3p, and 3d subshells, and the 4 th electron shell contains 4s subshell. The reason that came about in the first place was to support older browsers that didnt understand the new
syntax. Similarly, 2 represents the 2 nd electron shell, 3 represents the 3 rd electron shell, and 4 represents the 4 th electron shell. You can create a
element by using the document.createElement() method: In the following code, a br element is inserted before each span element in div.
Appropriate usage of the br element is to use it within a poem or an address. In the above image, 1 represents the 1 st electron shell. HTML elements with no content are called empty elements. HTML br (line break) element creates a line break in text within an HTML document.
