The length of time required for half of a sample of radioactive material to decay
If you mean HALF LIFE, that is the length of time it takes a quantity of a radioactive element to lose half its radioactivity.
DNA is not an element. DNA is the brain of the cell, and carries our genetics, traits, and characteristics of ourselves. It is not an element, but a microscopic, double-helix twisted strand that is miles and miles and miles long if it is unwound to its full length. It is not, however, an element.
It varies from one element to another. It is measured in terms of its half-life. A half-life is the length of time it takes for half the number of radioactive atoms of the element in a lump to decay.
The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds. Carbon skeletons can vary in length, branching, and ring structure.
Visible light has wavelengths ranging from approximately 400 to 700 nanometers. Different colors within the visible spectrum correspond to different wavelengths, with violet having the shortest wavelength and red having the longest.

Depending on the strength and length of exposure, yes it can.
They have equal measures.
neighborhood is a term for an area where people have settled and does not correspond to a measure of length
By convention the longer side is called the length, but it doesn't have to be. Consider a rectangular window: If you were to buy a blind for a window, the length of the blind would correspond to the drop from top to bottom of the window, and the width of the blind would correspond to the distance from side to side. If the window was a short, wide window the width of the blind would be longer than its length!
Different types of radioactivity have different amounts of energy and this directly impacts the half life. More energy will decrease the half life because it quickly gives off the unstable energy.
The bond length in silver is: 288.9 pm. One measure of size is the element-element distance within the element.

That all depends on the frequency of the sound and its speed in whatever substance it happens to be traveling through. In air, the wavelength of audible frequencies ranges from about 17.1 millimeters to about 17.1 meters. (20-20K Hz, 343 m/s)
Two entirely different types of measurements. One is a measurement of length, and the other is a measurement of volume. They don't correspond to each other.
The smallest (in mass and volume) element is hydrogen symbol: HIt has no specific length, so there's no 'short' one
