What is hassium found in?
1984
What does hassium mean?
: a short-lived radioactive metallic element produced artificially — see Chemical Elements Table.
What is Bohrium used for?
It decays into dubnium-266 through alpha decay. Since only a few atoms of bohrium have ever been made, there are currently no uses for bohrium outside of basic scientific research.
What does Bohrium mean?
: a short-lived radioactive chemical element that does not occur in nature and is produced by bombarding bismuth with chromium nuclei — see Chemical Elements Table.

What is an interesting fact about Bohrium?
Bohrium (Bh) has an atomic number of 107, and therefore has that same number of protons in the nucleus of each of its atoms. It is a synthetic element that is not naturally occurring on Earth. Interesting Bohrium Facts: Bohrium is one of the later discoveries, as it was not fully discovered until 1987.
What is the first halogen?
Physical and atomic
| Halogen | Standard atomic weight (u) | First ionization energy (kJ·mol−1) |
|---|---|---|
| Fluorine | 18.9984032(5) | 1681.0 |
| Chlorine | [35.446; 35.457] | 1251.2 |
| Bromine | 79.904(1) | 1139.9 |

What’s the meaning of halogen?
(Entry 1 of 2) : any of the five elements fluorine, chlorine, bromine, iodine, and astatine that form part of group VIIA of the periodic table and exist in the free state normally as diatomic molecules.
Why are Group 17 called halogens?
The elements of Group VIIA (new Group 17 – fluorine, chlorine, bromine, iodine, and astatine) are called the halogens (tan column). The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts.
Why is Group 16 called Chalcogens?
-Group-16 elements are also called chalcogens. They are called so because most of the copper ores have copper in the form of oxides and sulphides. They also contain small amounts of selenium and tellurium. So, group-16 elements are named chalcogens.
What is Group 2 called?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). In most cases, the alkaline earth metals are ionized to form a 2+ charge.
