To achieve stability, these atoms must make adjustments, particularly in their nuclei.
Each chemical element, such as carbon and oxygen, consists of atoms unique to it.
Each atom is understood to be made up of three basic parts.
The Slides are to be shown at the front and then each item is shown in turn and the pupils use their graphs to calculate the age of each item from the percentage of carbon found in them. take longer than you think, but keeps them engaged and there're questions to be answered in their books also.
Easily modified for different abilities, with my low ability I made all the percentages either 75%, 50% or 25% to make it much easier for them. The worksheets can be used in a number of ways, I used them in two ways, I laminated them both in the same pouch front to back for them to use as a mini whiteboard and write directly on them with a whiteboard pen then rub out the ink for reuse for different questions and classes and to use as group work.
Therefore, carbon has three isotopes, which are specified as carbon-12, carbon-13 and carbon-14 (figure 1). Comparison of stable and unstable atoms of the element carbon.
They have six protons in their nuclei and six electrons orbiting their nuclei, which gives carbon its chemical properties.
However, while the number of neutrons varies, every atom of any chemical element always has the same number of protons and electrons.
So, for example, every carbon atom contains six protons and six electrons, but the number of neutrons in each nucleus can be six, seven, or even eight.
Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.
