Answer:
As the options for the question not given, lets try to answer this question generally.
Explanation:
A reliable source can be described as an authentic source which proves or declines an action, research etc.
The most reliable source for scientific information is scientific papers. This is because scientific papers are subjected to peer- review and hence been tested and validated. A peer-review can be described as a judgement or test made by a person on other peoples research, both of the people having equal caliber.
Answer:
It cites valid data because a reliable scientific source needs data to back up what they’re proving.
Explanation:
A metallic bond is held together by electrostatic forces of interaction, while an ionic bond is held together by electrostatic forces of attraction by oppositely charged cations and anions. The ionic bond has one atom donate electrons to become positively charge while the other atom receives electrons and becomes negatively charged. The opposite charges then attract one another to create the electrostatic force of attraction. In contrast, the electrons in a metallic bond are delocalised, then the nucleus attracts this free moving electrons to establish electrostatic forces of interaction. The structure shows positive charge surrounded by negative charge.
