respectively—come together, the extra electron from chlorine can be given to sodium. This stabilizes the two atoms, the outer electron shells of both atoms are satisfactorily filled, and an ionic compound is formed, boasting a strong bond that will be more difficult to break than a covalent ...
The chemical formula for copper sulfate is CuSO4.x H2O, indicating that it is a covalent compound comprising copper, sulfur, and oxygen. Its crystalline structure and pleasant smell are evident from its chemical composition. Figure (1) shows the molecular structure of copper sulfate. ...
Gallium arsenide (GaAs) is a compound semiconductor with a band gap of 1.43 eV, which is larger than that of silicon. GaAs has a higher electron mobility than silicon, allowing for faster response times and higher-frequency operation. This makes GaAs an ideal material for hig...
Yes, valency determines whether an element forms covalent or ionic bonds. 7 Does valency vary among different elements? Yes, each element has a unique valency depending on its electron configuration. 6 Do all molecules have the same atomicity? No, atomicity varies based on the molecular formula ...
Give an example of a compound that has an ionic bond and explain how the ionic bond was formed. Which conditions suggest that a bond will be ionic? What attracts the atoms in an ionic bond? What makes a covalent bond? Is SO2 an ionic or covalent bond?
