Question

Химики сюда, срочно нужно определить количество протонов, нейтронов и электронов:1)Ca2)K3)Li4)Mn5)Alбуду очень благодарна :3​

Answer 1

Ответ:

1) Ca

p = 20

e = 20

n = 40-20=20

2) K

p = 19

e = 19

n = 39-19=20

3) Li

p = 3

e = 3

n = 6-3=3

4) Mg

p = 25

e = 25

n = 55-25=30

5) Al

p = 13

e = 13

n = 27 - 14

p - протоны

е - электроны

n - нейтроны

Answer 2

Calcium (Ca):

- Atomic number: 20 - Number of protons: 20 - Number of neutrons: 20 - Number of electrons: 20 [[1]]

Potassium (K):

- Atomic number: 19 - Number of protons: 19 - Number of neutrons: 20 - Number of electrons: 19 [[2]]

Lithium (Li):

- Atomic number: 3 - Number of protons: 3 - Number of neutrons: 4 - Number of electrons: 3 [[3]]

Manganese (Mn):

- Atomic number: 25 - Number of protons: 25 - Number of neutrons: 30 - Number of electrons: 25 [[4]]

Aluminum (Al):

- Atomic number: 13 - Number of protons: 13 - Number of neutrons: 14 - Number of electrons: 13 [[5]]

I hope this helps! Let me know if you have any other questions.
