A. what is the electron configuration of an isolated fe atom (no ligands bound to it)?

Explanation:

Iron (Fe) is a d-block element. The d-block elements are also known as transition metals. The atomic number of Fe is 26.

Therefore, for an isolated iron atom which is not attached to any ligands, the electronic configuration will be as follows.

radiation warms things up temp rises convection currents air circ windy weather

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
