The atomic number of an element, Z, is equal to the number of protons that defines the element. For example, all carbon atoms contain 6 protons in their nucleus; so the atomic number "Z" of carbon is 6. Carbon atoms may have different numbers of neutrons, which are known as isotopes ...
Each element's symbol is composed of a capital letter followed by one or two lowercase letters. Atomic Number- Each atom has an atomic number. This atomic number is equal to the number of protons in the nucleus of that particular atom. For example, the element cobalt (Co) has an atomic...
Which element has the highest first ionization energy? What is the third chemical element? What is the chemical symbol for dysprosium? What is the symbol for potassium on the periodic table? What is the name of the element that has an atomic number of 8? What is the most expensive chemical...
Note that when we were balancing the equation, we were thinking about the numbers of individualon each side, attending to theofofthat we can’t create or destroy atoms. When we’re thinking about proportions, however, we’re thinking about the coefficients in front of theparticles, which rep...
If it is a two-letter chemical symbol, only the first letter is capitalized. Often, the chemical symbol is the first or the first two letters of the name of the element. For example, the chemical symbol for oxygen is O, and the chemical symbol for helium is He....
According to the actinide concept by Seaborg [16], the 5f-electron series in the Periodic Table ends with element 103, lawrencium (Lr), and a new 6d-electron transition series starts with Z=104, Rf. After discovery of a long-lived α-particle emitting isotope with a half-life of 68 ...
