The Periodic Table
Water has a low melting point because:
The intermolecular forces are weak
The bonds between the hydrogen and oxygen atoms are very strong
There are no ions present
A single covalent bond involves the sharing of:
An element has the electron structure 2,8,6. To which group of the Periodic Table does it belong?
An element has the electron structure 2,8,8,2. To which period of the Periodic Table does it belong?
Element X has an electron structure of 2,8,5 and the structure of Y is 2,8,7. What is the most likely formula of the covalent compound formed by X and Y?
