WebThe mole is a unit used to measure the number of atoms, molecules, or (in the case of ionic compounds) formula units in a given mass of a substance. The mole is defined as the amount of substance that contains the number of carbon atoms in exactly 12 g of carbon-12 and consists of Avogadro’s number (6.022 × 10 23) of atoms of carbon-12. WebThis number (called the Atomic Number) determined how the atom behaved, i.e. what element it was. Hydrogen atoms have 1 proton and 1 electron, Oxygen has 8 of each, Uranium has 92 of each. The electrons were held in orbit by electric attraction (positive and negative attract), much as the planets were held in orbit around the sun by the ...

În fizică și chimie, numărul atomic al unui element chimic reprezintă numărul de protoni din nucleul atomilor acelui element și se notează de obicei cu Z. Numărul de electroni este egal, în cazul unui atom neutru din punct de vedere electric, cu numărul de protoni. Poziția elementelor chimice în sistemul periodic al elementelor este determinată de numărul Z, motiv pentru care acesta se mai numește și număr de ordine.
