Fluorine (F) would be least likely to form a cation out of potassium, fluorine, chlorine, and nitrogen.
- A cation is a positively charged atom (or molecule) that has lost electrons (or electrons).
- The tendency for electropositive elements to lose electrons and produce cations is greater. On the left side of the periodic table, these are often metals.
- Going down a group increases electropositivity, or the propensity to lose electrons and generate cations. and decreases across a period. In the given examples:
- Potassium, K is an alkali metal and will lose electrons readily to form a cation.
- Nitrogen (N), Fluorine (F), and chlorine (Cl) are all nonmetals that prefer to accept electrons and form anions instead. F is the most electronegative i.e. it will gain electrons and form F- rather than F+.

Answer:I believe it is c.
Explanation:
Since the speed of the bag is constant, it’s kinetic energy remains constant. Since it’s height above the ground is constant, it’s gravitational potential energy is also constant. Since it’s total energy is constant, net work = 0.
Answer:In astronomy, geography, and related sciences and contexts, a direction or plane passing by a given point is said to be vertical if it contains the local gravity direction at that point. [1] Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system.

Historical definition
Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book Perspective.
The word horizontal is derived from horizon,[2] whereas vertical originates in the late Latin verticalis, which is from the same root as vertex, meaning "highest point".[3]

Explanation:
Answer:
atoms have a positive nucleus and negative electrons,an atoms electron configuration the outermost electrons determines how the atom can interact with the other atoms and atom forms another atom for sharing electrons.
