Give the name and number of atoms of each element in the following compounds:
a. N2O, nitrous oxide, laughing gas
b. NH3, ammonia, a household cleaner
c. TiO2, titanium dioxide, white pigment used in paint
d. C8H10N4O2 caffeine, a stimulant
e. C19H25BN4O4 bortezomib, an anti-cancer drug
consult your periodic table for the names
Just count the atoms in the formula.
(d) C8 H10 N4 O2 has
8 C atoms, 10 H atoms, etc.
To determine the name and number of atoms of each element in a compound, we need to analyze its chemical formula. The number of atoms for each element is represented by subscripts following the element symbol.
a. N2O (nitrous oxide):
- Nitrous oxide consists of two nitrogen (N) atoms and one oxygen (O) atom.
b. NH3 (ammonia):
- Ammonia has one nitrogen (N) atom and three hydrogen (H) atoms.
c. TiO2 (titanium dioxide):
- Titanium dioxide contains one titanium (Ti) atom and two oxygen (O) atoms.
d. C8H10N4O2 (caffeine):
- Caffeine is composed of eight carbon (C) atoms, ten hydrogen (H) atoms, four nitrogen (N) atoms, and two oxygen (O) atoms.
e. C19H25BN4O4 (bortezomib):
- Bortezomib consists of nineteen carbon (C) atoms, twenty-five hydrogen (H) atoms, one boron (B) atom, four nitrogen (N) atoms, and four oxygen (O) atoms.
By examining the chemical formulas, we can determine the names and numbers of atoms for each element in the compounds.
