atom系一种element入面最细而且不能分割的部份,而Ion是由于atom/molecule得到或者失去electron时而令atom/molecule中的正负电荷失衡,得到净正或负电荷,咁ion都系element入面最细而且不能分割的部份?polyatomic ion系多过一个 atom 的 ion,咁他算不算系compound? 相关知识点: 试题来源: 解析 任

The ShK analogs generally comprise ShK toxin attached to a chemical entity (e.g. an atom, molecule, group, residue, compound, moiety, etc.) that has an anionic charge. In some embodiments the chemical entity attached to the ShK toxin may comprise an amino acid residue. The ShK analogs ...
Atoms of an element are all the same in terms of shape and size and atoms of different elements differ in size and shape. Elements are characterised by mass of their atoms so all the atoms of an element have identical weight. Different elements have atoms of different atomic weight. Atoms ...
A lithium molecule, Li2, is formed in the vapor state. The bonding occurs through the 2s atomic orbital of the valence shell of the lithium atoms, while the three-2p orbitals are empty (Fig. 6.34). As a result, there are six electrons in the molecule that have the configuration: σ1...

creates a graph that encodes different atomic interactions, enabling the construction of an inclusive and simplified representation of the dataset. Within this framework, atoms in the molecule, identified by these labels, are organized into subgraphs, and the colored edges signify element-specific ...
