Claire created a model to study the day and night cycle of earth as shown here. what causes different points on the globe to receive light at different times, explaining the day and night cycle of earth? the rotation of the lamp the revolution of the lamp the rotation of the globe the revolution of the globe

the rotation of the globe

Explanation:

As mentioned the model is representing the day and night cycle of earth thus the lamp must be the sun and the globe is earth.

The earth completes one year in taking one complete revolution around the sun (globe revolve around lamp).Thus due to revolution of earth the year gets completed.

The day and night of earth is due to rotation of earth on its own axis. The earth took 24 hours to complete one rotation on its axis.

Thus the rotation of globe causes it to receive light at different times.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
