Our own fixed network currently passes Virgin Media O2 is a major investor in the UK. As connectivity powers the nation through the pandemic and into the future, Virgin Media O2 will bring together next-generation gigabit broadband and 5G services while expanding its network reach across the country.
This includes delivering gigabit broadband speeds across our entire network footprint by the end of and we plan to upgrade our fixed network to full fibre to the premises with completion in Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry.
It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. The common confusion here is that two very different things have the same name. When we are just talking about the element, then just using the symbol by itself is clear. But sometimes we need to describe how the element appears in the world or in chemical reactions. Then it isn't enough to describe just the element, we need to know something about how it is found under normal conditions.
Oxygen is usually found as a diatomic gas which is why we write O 2. Since this is by far the commonest way we find free oxygen in nature we often describe it this way anyway unless there is a reason not to. Nitrogen is also mostly found in pure form as a diatomic gas N 2. Carbon, however, is usually found as a solid and never as a simple molecule diamond and graphite are both covalently bonded solids sort is rarely useful to describe its normal molecular form as there isn't one.
We might talk about sulfur as S or, if we care about the allotrope we might specify S 8 , though there are others common in the lab. It matters little which version you use to describe the element. But, if you are talking about reactions, it is usually worth describing the molecular form of the element you are talking about.
Oxygen isn't always O 2 but can be formed in the upper atmosphere or in some reactions as O 3. Chemists mix and match their terminology somewhat freely when it doesn't matter much, but try to be as specific as possible when it does. O is a singular oxygen atom. O 2 is a molecule made of two oxygen molecules.
Our atmosphere is made of mostly O 2 , which our bodies have evolved to breathe. O is oxygen, while O 2 is dioxygen. Examples of other oxygen molecules are: 0 3 which is ozone trioxygen , there's O 4 that is metastable and is actaully made up of two O 2 molecules tetraoxygen , and O 8 which is a form of pressurised solid O 2 when you freeze O 2 to below around 55 Kelvin and pressurise to around 10 GPa 1. Context is important. C is the atomic symbol for carbon and can represent not only the element, but one or more atoms of the element, as well as the element as it exists in the understood implied conditions.
Same is true for O or N or actually any element. However, elemental O and N are both commonly found as diatomic molecules O 2 and N 2. I will turn your question around: since oxygen and nitrogen are commonly represented by their ground state chemical compounds at STP why isn't carbon represented by C graphite?
It subsequently dropped the mm and adopted the pithier moniker O2. O2's advertising has featured the heavy or rather light use of air bubbles rising in water, with visually striking work that has used the instantly recognisable tones of actor Sean Bean as a voiceover. In , O2 published on YouTube a look back at a decade's worth of its ads.
The French and German marriage was consummated and Everything Everywhere was born, with its joint owners insisting that the name would not be consumer-facing. Everything Everywhere is shortened to EE, not long after chief executive Olaf Swantee described the original name as "silly". Although it housed both the Orange and T-Mobile brands, the latter has gradually been phased out of existence, stirring up controversy over unfair competition and resulting in an EU investigation.
Kevin Bacon is unveiled as the face of EE's advertising, with a debut ad that lasts an age and sees the 'Footloose' star using the parlour game 'The Seven Degress of Kevin Bacon' to push 4G and explain how everything is connected. The telecoms giant also admitted it is in talks with Telefonica about buying the O2 brand as Telefonica's chairman flies to the UK to enter talks.
