Not known
What will be the state of astatine at 20 degrees?
At 20 degrees Celsius, astatine would likely be a solid. Astatine is a rare and highly radioactive element with a melting point of around 302 degrees Celsius, so it would typically exist as a solid at room temperature.
Which elements in group 7 are solids at 20 degrees celsius?
iodine and Astatine
What are the melting and boiling points of astatine?
Astatine is a radioactive element and its melting point is estimated to be around 302 degrees Celsius (576 degrees Fahrenheit), while its boiling point is estimated to be around 337 degrees Celsius (639 degrees Fahrenheit).
What is the boiling point of astatine?
The boiling point of astatine is approximately 337 degrees Celsius. Astatine is a rare and highly radioactive element that exists only in trace amounts in nature. Due to its radioactivity and scarcity, it is challenging to study its properties in detail.
Which place is at 0 degrees and 77 degrees west?
The point at 0 degrees latitude and 77 degrees west longitude runs through the central part of the South American country, Brazil. The coordinates intersect in the Amazon Rainforest region, which is known for its rich biodiversity and dense vegetation.
What substance has a boiling point of 400 degrees Celsius?
The boiling point of astatine is 400 oC.
Is water more dense at 100 degrees Celsius?
More dense than what? I presume you mean is it more dense at that temperature than at lower temperatures. The answer is no, it gets denser at lower temperatures, all the way down to 4 degrees centigrade. Then it gets less dense again.
What is less dense than water at 4 degrees Celsius?
Ice. It expands when it's 0 degrees Celsius.
Can you make ice at 4 degrees?
Yes. Frozen ice is less dense than liquid water. That is why ice cubes float in your drink! In fact at positive 4 °C, water is the most dense. Colder than that, and the density decreases, and also warmer than that, the density decreases.
What is 0 degrees and 0 degrees?
0 degrees...
What type of element is astatine?
Astatine is an element with the symbol At.
