| vocabulary简明 | The nucleus of an atom includes a proton, which has a positive charge, an electron, which has a negative charge, and neutron, which has no charge, or is "neutral." The hydrogen atom is the only atom without a neutron. |
| vocabulary扩展 | The basis for the word neutron is both "neutral" and the suffix "-on," which probably comes from the Greek ión, "to go." The word ion first appeared in English in 1834, and neutron appeared in 1921, to represent the neutral part of an atom. Don't let the "neutral" part fool you, though — a neutron bomb, while "smaller" than other nuclear weapons, is still capable of mass destruction, as it emits more radiation, causing a wider sweep of damage to life. |
