an element p has atomic number 13 while q has the atomic 16..write down electric configuration of p and q

Explanation:

p=1s^2,2s^2,2p^6,3s^2,3p^1

q=1s^2,2s^2,2p^6,3s^2,3p^4

the quantum numbers are used in my answer.

there are 4 quantum numbers.

1.principal quantum numbers

2.angular momentum quantum numbers

3.magnetic quantum numbers

4.spin quantum numbers

In this case,the angular momentum quantum numbers is being used.it describes the unique quantum state of an electron and is designated by the letter L.this behaviour manifests itself as the shape of the orbital.electron shells have distinct shapes denoted by letters,s,p,d,f.

l can be numbers like,0,1,2,3

the maximum electrons in each letter is,

s=2

p=6

d=10

f=14

the shapes of the sub_shells

s sub_shell is spherical

p sub_shell is two dumb_bells

d sub_shell is four dumb_bells

f sub_shell is eight dumb_bells

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.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
