Why? a. All carbon atoms are identical. b. An oxygen atom combines with 1.5 20 hours ago Dutch Translation for lead atom - dict.cc English-Dutch Dictionary 2019-02-10 2018-10-01 A lead atom has 82 electrons, arranged in an electron configuration of 4f 14 5d 10 6s 2 6p 2. The sum of lead's first and second ionization energies—the total energy required to remove the two 6p electrons—is close to that of tin, lead's upper neighbor in the carbon group. Lead is a chemical element with atomic number 82 which means there are 82 protons and 82 electrons in the atomic structure.

2015-11-22 · 6.6 * 10^(22)"atoms" You know that the mass of an individual lead atom is equal to 3.4 * 10^(-22) grams. A substance's density tells you what its mass per unit of volume is. In this case, you know that lead has a density of "11.3 g/cm"^3, which means that each "cm"^3 of lead will have a mass of "11.3 g".

Tyrannosaurus rex var dinosauriernas kung. Läs allt om A lead atom has 82 electrons, arranged in an electron configuration of 4f 14 5d 10 6s 2 6p 2. The sum of lead's first and second ionization energies—the total energy required to remove the two 6p electrons—is close to that of tin, lead's upper neighbor in the carbon group. Lead has atomic number 82, which means each lead atom has 82 protons. This is the highest atomic number for the stable elements. Natural lead consists of a mixture of 4 stable isotopes, although radioisotopes also exist.
