An unknown element has two stable isotopes. 92.41 percent of all atoms of this element have a mass number of 7. The remaining 7.59
percent of atoms of this element have a mass number of 6. Which of the following is MOST LIKELY to be true about the average atomic mass
of the unknown element
The average atomic mass is slightly lower than 7 but much higher than 6.
The average atomic mass is 6.5
There is no way to estimate the average atomic mass without knowing the identity of the element.

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.
