名詞

(chemistry) A rule stating that atoms lose, gain, or share electrons in order to have a full valence shell of 8 electrons. (Hydrogen is excluded because it can hold a maximum of 2 electrons in its valence shell.)

日本語の意味

化学において、原子が8つの価電子を持つために電子を失ったり、得たり、共有したりする規則。ただし、水素は最大2電子までしか保持できないため、例外とされる。

Under the octet rule, atoms tend to gain, lose, or share electrons to achieve a full valence shell of eight electrons.

オクテット則に従い、原子は価電子殻を8個で満たすために電子を失ったり、獲得したり、共有したりして結合を形成する傾向があります。

意味（1）

(chemistry) A rule stating that atoms lose, gain, or share electrons in order to have a full valence shell of 8 electrons. (Hydrogen is excluded because it can hold a maximum of 2 electrons in its valence shell.)

意味（2）
