1/8 amount of the element will reamain.
After 1 half-life there is 1/2 left
After the 2nd half-life there is 1/2 of 1/2 left which is 1/4
After the 3rd half-life there is 1/2 of 1/4 left which is 1/8

What do forensic anthropologist do?
Forensic anthropology is the examination of skeletal remains. A forensic anthropologist can first determine if the remains are in fact human. Then he can determine the gender, approximate age, physical stature, their occupation, and likely racial affiliation of the person in life. He can also estimate approximate time since death, likely cause of death and any identifying illnesses or wounds suffered in life that could leave traces in the bone structure.
What is a forensic anthropologist?
Forensic anthropology is the application of the science of physical anthropology and human osteology (the study of the human skeleton) in a legal setting, most often in criminal cases where the victim's remains are more or less skeletonized. A forensic anthropologist can also assist in the identification of deceased individuals whose remains are decomposed, burned, mutilated or otherwise unrecognizable. The adjective "forensic" refers to the application of this sub field of science to a court of law. Answer: Forensic anthropology is the examination of skeletal remains. A forensic anthropologist can first determine if the remains are in fact human. Then he can determine the gender, approximate age, physical stature, their occupation, and likely racial affiliation of the person in life. He can also estimate approximate time since death, likely cause of death and any identifying illnesses or wounds suffered in life that could leave traces in the bone structure.Generally speaking forensic anthropology is the examination of human skeletal remains for law enforcement agencies to determine the identity of unidentified bones. Further definition of the term is necessary to understand the scope and basis of forensic anthropology. Anthropology alone is the study of man. Anthropologists are interested in culture (cultural anthropologists), language (linguistic anthropologists), the physical remains or artifacts left behind by human occupation (archaeologists), and human remains or bones and teeth (physical anthropologists).
What is the name for a number that is not prime or composite?
I will assume you mean "positive integers". In this case, the only number that is considered neither prime nor composite is the number 1. 1 has the special role of the identity element of multiplication, meaning that if you multiply a number by 1, it remains unchanged.
What is anaploidy?
Anaploidy remains undefined.
What is infinite divided by zero?
The answer remains infinity
What remains a vital element in crime detection?
The most vital element in crime detection and criminal investigation is the human element.
What happens to the mass of an element when it burns?
When an element burns, its mass remains the same. The burning process involves a chemical reaction that rearranges the atoms of the element, but the total mass of the element before and after burning remains constant, according to the law of conservation of mass.
Does an element split up when a current passes through it?
An element does not split up when a current passes through it. The current causes electrons to flow through the element, but the element remains intact.
Is a radioactive sample has decayed until only one eighth of the original sample remains unchanged how many half lives have elapsed?
Three half lives have elapsed. This can be determined by calculating how many times the original sample size must be halved to get to one eighth: (1/2) * (1/2) * (1/2) = 1/8.
What fraction of the radioisotope remains in the body after one day?
If an isotope is absorbed into the body, the fraction that remains after one day depends on the radiological half-life of the isotope and the biological half-life (basically how fast the element can be eliminated from the body) of the element that the isotope represents.
The first element in a binary compound should have no change?
In a binary compound, the first element is usually a metal or a positively charged ion, and its name remains the same as the element itself without any changes.
What element has no gas phase?
Helium is an element that has no gas phase. It remains a gas at all temperatures, without undergoing a phase change.
What part of an element is the same?
The number of protons in the nucleus of an element remains the same, as this defines the element's identity. The number of protons is what determines the atomic number of an element on the periodic table.
A what usually does not change and remains the same throughout a story?
A theme is an element that typically does not change and remains consistent throughout a story. Themes are central ideas or messages that the author conveys to the reader.
How long will it take a g sample of bismuth to decay such that 2.0 g of the element remains?
You forgot to say that isotope is.
What was the day that Caylee Anthony died?
It was determined that Caylee Anthony's approximate date of death was June 16, 2008. Her remains were not discovered until December 11, 2008.
Does the element change when the atomic mass changes?
No, the element remains the same even when the atomic mass changes. Atomic mass is determined by the number of protons and neutrons in the nucleus of an atom, but changing the number of neutrons does not change the identity of the element.
