For example : 5200 is written as,

a) 4,680,000,000

This number is written in scientific notation as

the answer is a

photosynthesis

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
