Kinetic energy is energy in motion. Which of these isn't in motion?
A lady walking slowly but surely down a street is moving, right? So that isn't right.
A hockey puck sliding on ice has motion.
A man running around a track definitely demonstrates kinetic energy.
But, a baseball glove doesn't. Maybe if it's moving on someone's hand, but by itself, it isn't moving.
Answer: The bond formed between magnesium and oxygen is an ionic bond.
Explanation:
An ionic bond is formed when an atom transfer its valence electrons to another atom.
Whereas, a covalent bond is formed by the sharing of electrons between the atoms.
Silicon and oxygen forms silicon dioxide. Silicon has 4 valence electrons which are shared with each oxygen atom. Hence, silicon and oxygen forms a covalent bond.
Oxygen and oxygen shares two pairs of electrons therefore, a covalent bond is formed between oxygen and oxygen.
A covalent bond is formed between carbon and hydrogen as carbon has 4 valence electrons which are shared with four hydrogen atoms.
Magnesium has 2 valence electrons which are transferred to the oxygen atom in order to complete its octet.
Therefore, the bond formed between magnesium and oxygen is an ionic bond.
Carpenters use nails instead of screws. If that isnt the answer you are looking for than another answer would be that screws hold better than nails. When you screw wood together they don't slide or turn sideways like when you nail wood together. When they are nailed together you can turn the two pieces of wood while they are stuck.
