2. MINUTE TO READ
Once upon a time a daughter complained
to her father that her life was miserable and
that she didn’t know how she was going to
make it. She was tired of fighting and
struggling all the time. It seemed just as one
problem was solved, another one soon
followed.

3. Her father, a chef, took her to the kitchen.
He filled three pots with water and placed
each on a high fire. Once the three pots
began to boil, he placed potatoes in one pot,
eggs in the second pot, and ground coffee
beans in the third pot.
He then let them sit and boil, without
saying a word to his daughter. The daughter,
moaned and impatiently waited, wondering

4. After twenty minutes he turned off the
burners. He took the potatoes out of the
pot and placed them in a bowl. He pulled
the eggs out and placed them in a bowl.
He then ladled the coffee out and placed
it in a cup. Turning to her he asked.
“Daughter, what do you see?”

5. “Potatoes, eggs, and coffee,” she hastily
replied.
“Look closer,” he said, “and touch the
potatoes.” She did and noted that they were
soft. He then asked her to take an egg and
break it. After pulling off the shell, she
observed the hard-boiled egg. Finally, he
asked her to sip the coffee. Its rich aroma
brought a smile to her face.

6. He then explained that the potatoes,
the eggs and coffee beans had each
faced the same adversity– the boiling
water.
However, each one reacted
differently.
The potato went in strong, hard, and
unrelenting, but in boiling water, it

7. The egg was fragile, with the thin outer shell
protecting its liquid interior until it was put in the
boiling water. Then the inside of the egg became
hard.
However, the ground coffee beans were unique.
After they were exposed to the boiling water, they
changed the water and created something new.
“Which are you,” he asked his daughter. “When
adversity knocks on your door, how do you
respond? Are you a potato, an egg, or a coffee

8. LESSON:
“In life, things happen around us,
things happen to us, but the only
thing that truly matters is what
happens within us.”

34. NOMENCLATURE OF BINARY COVALENT
COMPOUNDS
1.Name the first element in the compound.
2. Name the second element using its ROOT NAME
3. Add the suffix –ide to the root name of the second element
4. Use prefixes for each element to indicate the number of
each type of atom in the formula unit

35. NOMENCLATURE OF BINARY COVALENT

40. EXAMPLE: N2O5
Rule 1: NITROGEN
Rule II: OXYGEN = ROOT NAME: OX-
Rule III: OXIDE
Rule IV: NITROGEN HAS 2 ATOMS AND OXYGEN HAS 5
NITROGEN: DI OXYGEN: PENTA
DINITOGEN PENTAOXIDE

41. EXAMPLE: P4S9
Rule 1: PHOSPHORUS
Rule II: SULFUR = ROOT NAME: SULF-
Rule III: SULFIDE
Rule IV: PHOSPHORUS HAS 4 ATOMS AND SULFUR HAS 9
PHOSPHORUS: TETRA SULFUR:NONA
TETRAPHOSPHORUS NONASULFIDE

42. EXAMPLE: SO2
Rule 1: SULFUR
Rule II: OXYGEN = ROOT NAME: OX-
Rule III: OXIDE
Rule IV: SULFUR HAS 1 ATOM AND OXYGEN HAS 2
SULFUR: MONO OXYGEN: DI

43. EXAMPLE: SO2
Rule 1: SULFUR
Rule II: OXYGEN = ROOT NAME: OX-
Rule III: OXIDE
Rule IV: SULFUR HAS 1 ATOMS AND OXYGEN HAS 2
SULFUR: MONO OXYGEN: DI
NOTE: IF THE FIRST ELEMENT HAS ONLY 1
ATOM, NO NEED TO USE FREFIX MONO

44. EXAMPLE: SO2
Rule 1: SULFUR
Rule II: OXYGEN = ROOT NAME: OX-
Rule III: OXIDE
Rule IV: SULFUR HAS 1 ATOMS AND OXYGEN HAS 2
SULFUR: MONO OXYGEN: DI
SULFUR DIOXIDE
NOTE: IF THE FIRST ELEMENT HAS ONLY 1
ATOM, NO NEED TO USE FREFIX MONO

57. GUIDE QUESTIONS:
• Explain the significance of using prefixes in the names
of covalent compounds.?
• Why is it important to follow systematic
nomenclature when naming covalent compounds,
and what challenges may arise if the rules are not
adhered to?
