我係Form 3student
我想問上咩叫covalent bond??
我睇完wiki都唔明
係咪 2 kinds of non-metal element shared outermost shell
let it be full outermost shell?
electron attract atomic nucleus ?
molecules 同covalent bond 有咩關係？？

✔ 最佳答案

即係當兩個bond一齊分享佢地既electron, 通常covalant bong 都係為左要full outer shell.

molecule 同 atom 唔同。molecule 係 2(or more than 2)個atom 在一起既時候先可以叫molecule.

兩句都錯.
Bonds don't share electrons; electrons are shared to form bonds.
Monoatomic molecules, such as helium & argon.
