Since the iodine is added as a 1− anion, the number of electrons is 54 [53 – (1–) = 54]. Exercise 1.3.1. An ion of platinum has a mass number of 195 and contains 74 electrons.
WitrynaThe atomic mass unit (u or amu) is a relative unit based on a carbon-12 atom with six protons and six neutrons, which is assigned an exact value of 12 amu's (u's). This is the standard unit for atomic or molecular mass, and 1 amu is thus 1/12 th the mass of a 12 C atom. This is obviously very small. 1 amu = 1.66054x10-27Kg = 1.66054x10-24 g. Witryna1 lip 2024 · As a result, a neutral atom must have an equal number of protons and electrons. The atomic mass unit (amu) is a unit of mass equal to one-twelfth the …
Witryna22 paź 2024 · The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. Therefore, the atomic number of an atom also tells you how many electrons the atom has. This, in turn, determines many of the atom’s chemical properties.
WitrynaThe atomic number of the element is expressed by ‘Z’. This number is equal to the serial number of the periodic table.
