aInaccurate 不精确 [translate] a4、 例如:Each atom normally has the same number of electrons, revolving about the nucleus as it has protons(质子). 4、例如:因为它有氢核质子,每个原子通常有电子的同一数量,旋转关于(中坚力量)。 [translate] ...
The mass number is the sum of the number of protons and the number of neutrons in an atom. In-ground state, the total charge in an atom is zero. This is because the number of protons is equal to the number of electrons. If an atom acquires electrons, it g...
Find the Number of Protons Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton ...
