Look at the amount of energy it takes to remove a valence electron from He, Ne, Ar, Kr, and Xe compared to atoms in the same period (row). Based on what you know about ionization energy, why
what does that tell you about the tendency of these elements to react with other elements?

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

One similarity and one difference between an element and a mixture of elements

4786 joules of heat are transferred to a 89.0 gramsample of an unknown material, with an initialtemperature of 23.0°c. what is the specific heat of thematerialif the final temperature is 89.5 °c?
