Question

Subatomic particles are ________.

A
Located inside of an atom


B
Composed of many atoms


C
The smallest possible form of matter


D
Classified on the periodic table

Answer 1

Glucose is a very large sugar molecule made from six atoms of carbon, twelve atoms of hydrogen and six atoms of oxygen. How many atoms are in one molecule of glucose?

A
36


B
12


C
48


D
24

Answer 2

An electron cloud is mostly made up of _____.

A
protons


B
neutrons


C
electrons


D
empty space

Answer 3

The correct answer is:

A. Located inside of an atom

Subatomic particles, such as protons, neutrons, and electrons, are the particles that make up an atom. They are not classified on the periodic table, and while they are among the smallest particles known, they are not necessarily the smallest possible form of matter, as there are particles even smaller than them, like quarks.

Answer 4

To find the total number of atoms in one molecule of glucose (C₆H₁₂O₆), you simply add the number of each type of atom:

- Carbon (C): 6 atoms
- Hydrogen (H): 12 atoms
- Oxygen (O): 6 atoms

Now, add them together:

6 (C) + 12 (H) + 6 (O) = 24 atoms

So, the correct answer is:

D. 24

Answer 5

The correct answer is:

C. electrons

An electron cloud refers to the region around an atom's nucleus where electrons are likely to be found. While it may be conceptually thought of as mostly "empty space," the term "electron cloud" specifically pertains to the presence of electrons themselves, which occupy this region around the nucleus. Thus, it is primarily made up of electrons.
