Calculate the number of neutrons in the chlorine 17Cl35 and 17Cl37 ?

chlorine 17Cl35 has 18 neutrons, and 17Cl37 has 20 neutrons

Explanation: 17 is the atomic number of chlorine which tells us what is the number of protons in chlorine nucleus. 35 and 37 is the mass number of two isotopes of chlorine, it tells us what is the total number of protons and neutrons in atomic nucleus of two chlorine isotopes .

Now to know how many neutrons are in both isotopes we have to substract the number of protons from the mass number of each isotope

For 17Cl35 it will be 35- 17 what makes 18 and for 17 Cl 37 it will be 20 neutrons

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
