Place the atoms relative to each other. Place the atom with group number in the center because it has the electronegativity. If atoms have the same group number, place the atom with the period number in the center.

Place the atoms relative to each other. Place the atom with lower group number in the center because it has the lower electronegativity. If atoms have the same group number, place the atom with the higher period number in the center.

Explanation:

Generally, electronegativity increases from left to right within a period (horizontal rows in the periodic table), and decreases from top to bottom within a group (vertical columns).

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
