Answer to Problem 85AP
The chemical symbol of astatine is At and its atomic number is 85.
Explanation of Solution
There are in total 118 elements known to exist in nature shown in the periodic table. Every element in the nature has given its own symbol, which is a shorthand method for representing the element. It is an easy way to represent the element by symbol instead of writing out the name of an element. The symbol of the element can be represented by one or two letters. For two letter symbols, only first letter is capitalized. The number of protons present in the nucleus of an atom signifies the atomic number of the atom, the atomic number is unique for every element.
Thus, chemical symbol of astatine is At and its atomic number is 85.

Which particles make the greatest contribution to the chemical properties of an atom?arrow_forwardThe existence of isotopes violates one of the original ideas of Dalton’s atomic theory. Which one?arrow_forwardState the main points of Dalton’s atomic theory usingyour own words. Which parts of Dalton’s theory werelater found to be erronous? Explain why.arrow_forward
- Thomson and Rutherford helped to show that atoms consist of three types of subatomic particles, two of which are charged. What if subatomic particles had no charge? How would this affect what you have learned?arrow_forwardYour friend tells you about an article that he read in a tabloid that reported the discovery of a new form of carbon containing eight protons in the nucleus of its atoms. He claims that scientists are eager to explore the properties of this new form of carbon. What is wrong with the tabloid's claim? a. Nothing. The claim is believable. b. The claim must be false because an atom with eight protons would be oxygen, which is already known. c. The claim must be false because all forms of carbon are already known.arrow_forwardThe isotope Si-28 has a mass of 27.977 amu. For ten grams of Si-28, calculate (a) the number of atoms.
