A proton is an elementary particle of matter that (拥有) a positive charge.相关知识点: 试题来源: 解析 possesses 本题考查动词解题步骤:1. 分析句意:质子是带正电荷的物质的基本粒子。2. 确定答案。根据中文提示"拥有",确定单词为possess。句意为客观真理,因此应用三单形式,故本空填possesses。
The charge of the proton is a positive charge. The nucleus of the atom is made up of the positively charged protons and negatively charged neutrons. The positive charge that is carried by the proton is called a +1 elementary charge, the exact opposite of the negative charge that is carried...
A proton is a subatomic particle found in the nucleus of atoms that differs from the other subatomic particles (called neutrons) in the nucleus of most atoms because each proton has a positive charge of +1 (as opposed to neutrons, which have no charge).
