What is the meaning of francium?
Francium is a highly radioactive alkali metal element with the atomic number 87 and symbol Fr. It is the second rarest naturally occurring element in the Earth's crust and is extremely unstable, making it difficult to study. Francium was discovered in 1939 by Marguerite Perey.
The modern term Hertz means?
The modern term Hertz refers to a unit of frequency measurement, symbolized as Hz, named after the German physicist Heinrich Hertz. It is commonly used to measure the number of times a wave cycles per second, such as in radio waves and electrical currents.
This is the second era in geologic time?
The second era in geologic time is the Paleozoic Era, which lasted from about 541 million years ago to 252 million years ago. It is known for the Cambrian explosion, the development of complex multi-cellular life forms, and the presence of early terrestrial plants and animals. Major events in this era include the colonization of land by plants and arthropods, as well as the diversification of marine life.
What is your annual contribution of carbon dioxide in the atmosphere?
According to the National Oceanic and Atmospheric Administration (NOAA), the daily average concentration of carbon dioxide in Earth's atmosphere surpassed 400 parts per million for the first time in human history. The world emits 2.4 million pounds of CO2 per second.
At what speed do electromagnetic waves travel through space?
It travels at the "speed of light". In vacuum, that's 299,792,458 meters per second. In any kind of material substance, it's less. How much less depends on the individual substance ... they're all different.
How many feet in 8 million?
That would be 8 million feet in 8 million. As you didnt specify the second unit of measurement (8 million of what?), I would just presume its the same as the first unit of measurement you provided
What is the unit of measurement speed of processors?
MIPS:- Million Instruction per Second.
How fast is the sun making nuclear fusions?
Fast enough to convert 4 million tons of mass to energy, every second.Fast enough to convert 4 million tons of mass to energy, every second.Fast enough to convert 4 million tons of mass to energy, every second.Fast enough to convert 4 million tons of mass to energy, every second.
What is the second most reactive metal?
The 2nd most reactive is Cesium after Francium. If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.
One tmc is equal how many liters per second?
A TMC is the acronym for Thousand Million Cubic Feet. This doesn't translate easily into liters per second because one is an area measurement and the other is a volume measurement.
What is the measure of cycles per second in computer processing?
A 'Hertz' is a cycle of once a second. A megaHertz is a million cycles per second.
Does francium have any older names?
Yes, Francium has a couple older names. The first time it was discovered, it was called "eka-caesium." The second name was "moldavium."
What is the meaning of francium?

All alkali metals except francium had been disconerd by 1860 why did it take scientists another 80 years to find francium?
Francium is the second rarest element on earth so that's probably why it took a little longer to discover.
Galileo's measurement in meters per second?
The measurement was 5000 metres per second
What are 3 unusual facts about francium?
Francium is the second rarest naturally occurring element on Earth. It is highly radioactive and has a very short half-life, making it difficult to study and isolate. Due to its extreme rarity and radioactivity, francium is primarily used for scientific research and has no practical applications.
How fast could you get around the world going 71 million cubic feet per second?
Well, cubic feet is a measurement of area, so if you take away cubic, going 71 million feet per second, the answer is about 2 seconds, if you went around the equator.
