Question

identify the element
use each clue to determine the element.
you will need to use a periodic table.
clue: i have 7 protons and a mass of 14.
what element am i?

clue: what element is represented in the
bohr model below?

clue: i have 9 protons and a total of 28
subatomic particles. what element am i?

clue: the blocks below represents the
number of protons, electrons and neutrons
in an element. what element am i?

clue: ape - man was completed for an
element. according to the calculations,
which element am i?
a = 19 m = 39
p = 19 a = -19
e = 19 n = 20

Explanation:

Step1: Use proton count for element 1

Proton count = atomic number = 7. The element with atomic number 7 is Nitrogen (mass number 14 matches common isotope).

Step2: Use proton count for element 2

Bohr model shows P=3. Atomic number 3 is Lithium.

Step3: Calculate neutron count for element 3

Total subatomic particles = protons + neutrons + electrons. For neutral atoms, electrons = protons =9. Neutrons = 28 - 9 -9 =10. Atomic number 9 is Fluorine.

Step4: Use proton count for element 4

Block shows P=2. Atomic number 2 is Helium (corrected from the written answer).

Step5: Use proton count for element 5

APE-MAN shows P=19. Atomic number 19 is Potassium.

Answer:

1. Nitrogen
2. Lithium
3. Fluorine
4. Helium
5. Potassium
