The correct answer is
<span>requires more energy to lose an electron than a metal
In fact, the main characteristics of the metals is that they have many electrons free to move through the lattice of the material, so it is easy for a metal to gain/lose electrons. On the contrary, non-metals don't have free electrons, so more energy is required in order to rip an electron from the atoms of the material.</span>
Answer:
Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.
Answer:
Mass is the measure of an object's matter (what it's made up of). The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system.
