Arsenic (in the form of arsenic-75) is a stable element. Only its isotopes have a half-life. As there are many isotopes of every element, and each has a different half life, it is difficult to specify a precise answer.
The related link below contains a list of known isotopes and their half lives.
You say 'I've missed Half my life' which is short for : "I have missed half my life'
No. Half-Life: Source runs on the Source engine. The original Half-Life doesn't. You cannot use mods made for the original Half-Life on Half-Life: Source because they run on different engines and it won't work.
Half-Life, Half-Life: Blueshift, Half-life: Opposing Force, Half-life: High Definition pack (might not classify as a game), Half-Life: Source, Half-Life 2, Half-Life 2: Episode 1, and Half-Life 2: Episode 2. Eight games total not including countless mods created by fans that you can download for free on moddb.com and fileplanet.com. Other games by Valve software include Left 4 Dead, Left 4 Dead 2, Portal, Portal 2, Counter Strike, Counter Strike: Source, Team Fortress, Team Fortress 2, and Alien Swarm. Another Half-Life game would be Half-Life: Decay. You might also be able to count Half-Life Deathmatch and Half-Life 2 Deathmatch.
There is something called Decay on the first half-life where you play as two women during the incident. There is also a half-life 2: deathmatch, and that's more or less it. There is Half-Life Deathmatch and Half-Life Deathmatch: Source. You can also download a mod, "Sven Co-op", which allows you to play the Half-Life story with other players.
no, but you do need a source game like Half Life, Half Life2, or Team Fortress2
Some bacteria can use arsenic for the life.
you
no go ahead and tell me how it works out
The only stable, and thus by far the most common, isotope of arsenic is arsenic-75, although isotopes have existed from arsenic-60 through arsenic-92. The isotopes with the longest half-lives are arsenic-73, arsenic-74, and arsenic-76.
For every gallon of elderberry wine they used one teaspoon of arsenic, half a teaspoon of strychnine and a pinch of cyanide.
Arsenic has three electrons occupying the three 4p orbitals in its valence shell. Hund's first rule tells us that they will each occupy separate orbitals before they start to pair up. So there are three half-filled orbitals in an arsenic atom.
It isn't. Arsenic is a poisonous substance; most people won't use it, unless they work in very specialized areas.
carbon is used in rat poison and is the title of a murder mystery
Arsenic is an element. The scientific name for arsenic is arsenic. Arsenic's chemical symbol is: As It is left to the student to balance the chemical equation of Arsenic and Old Lace.
Naturally occurring arsenic is composed of one stable isotope, 75As.[11] As of 2003, at least 33 radioisotopes have also been synthesized, ranging in atomic mass from 60 to 92. The most stable of these is 73As with a half-life of 80.3 days. Isotopes that are lighter than the stable 75As tend to decay by β+ decay, and those that are heavier tend to decay by β- decay, with some exceptions. At least 10 nuclear isomers have been described, ranging in atomic mass from 66 to 84. The most stable of arsenic's isomers is 68mAs with a half-life of 111 seconds
1. Arsenic is used in weed killers, and pesticides (poison for pests like mice/bugs), and other poisons 2. Arsenic can be used as a semi-conducter (Like boron) 3. Arsenic can be used in medical treatments (such as arsenic trioxide) 4. Arsenic is used as a wood preservative 5. Arsenic is used for alloying with copper and lead to form various useful materials
Strictly, there are no other "chemicals" in arsenic, because arsenic is a chemical element, and pure arsenic therefore does not contain any other element.
