laila [671]

Answer:

The statement that best describes the vascular tissue in seed plants is that xylem carries water and nutrients from the roots to the rest of the plant.

Explanation:

Xylem corresponds to the tissue of the vascular plants that is responsible for the transport and distribution of liquids necessary for their development.

Show a diagram of how ions are formed when a sodium atom comes into close

Firdavs [7]

Answer:

The diagram is attached below.

Explanation:

when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.

Both atoms bonded together through ionic bond.

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
