Explain what a cation is and in terms of electrons, why does it have a positive charge. explain what an anion is and why anions have a negative charge. what type of bond would these ions form?

Explanation:

Cation:

When an atom lose the electron positive charge is created on atom and atom is called cation.

Anion:

When an atom accept an electron negative charge is created on atom and it is called anion.

Electron have negative charge that's why when in loses from atom negative charge become less and positive charge is increased that's why atom when lose the electron have positive charge.

When atom accept the electron one more negative charge is created and anion is formed because of this negative charge.

When both anion and cations are combine ionic bond is formed.

For example:

sodium atom loses its one valance electron and form cation Na⁺ chlorine atom gain one electron and form anion Cl⁻. both combine to form sodium chloride through ionic bond.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
