Question 4 Mr Zapata is putting his flyboard design through an improvement phase by using his engineering
and scientific knowledge to increase the weight load that the Flyboard can handle to increase sales
of his invention.
So, he wants to increase the maximum capacity (the most amount of mass that the machine can
carry) of his Flyboard from 100kg to 200 kg. To achieve this goal, what feature of the machine
MUST Zapata improve?
90kg rider
100 kg rider with 50kg of gear = 150 kg
A) The length of time the machine can fly. B) amount of fuel that the machine can hold C)the speed that the machine can fly D)the force that the machine can exert

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

explanation

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.
