a Complete these sentences by deleting the incorrect word in each pair. Atoms of the same element have the same number of protons/neutrons The number of protons / neutrons in an atom is called its proton I mass number. The number of protons plus the number of electrons / neutrons in an atom gives the atomic / nucleon number. As an atom is neutral, the number of negative electrons / neutrons in an atom is always the same as the number of positive protons in the nucleus. b Complete the following sentences using the words below to fill the gaps. The... __ in an atom are not free to move where they like. They can only occur at fixed distances from the nucleus in electron __ .(or __ levels). The first shell, __ ................ to the nucleus, can only take two electrons while the second shell can take up to.... __ electrons.

Cevap

a. Atoms of the same element have the same number of protons. The number of protons in an atom is called its atomic number. The number of protons plus the number of neutrons in an atom gives the mass number. The number of protons plus the number of neutrons in an atom gives the atomic / nucleon number. As an atom is neutral, the number of negative electrons in an atom is always the same as the number of positive protons in the nucleus.<br /><br />b. The electrons in an atom are not free to move where they like. They can only occur at fixed distances from the nucleus in electron shells (or energy levels). The first shell, closest to the nucleus, can only take two electrons while the second shell can take up to eight electrons.
