Question

match each scientific term with its correct definition: (5 points)
theory
octet rule
law
period
atomic number
group
a testable prediction about an experimental outcome
a collection of elements forming a single column on the periodic table
indicates the number of protons in an atom of an element
sum of protons and neutrons in an atom
an area in which the electrons of an atom orbit the nucleus
electrons found in the orbital farthest from the nucleus

Answer:

To solve this matching problem, we analyze each scientific term and its correct definition:

1. Theory

A theory in science is a well - substantiated explanation of some aspect of the natural world, but the given option "A testable prediction about an experimental outcome" is actually the definition of a hypothesis. There seems to be an error in the provided matches. However, if we assume a mislabeling and consider the closest (though incorrect as per standard definitions), but likely the intended match (maybe a typo) for theory - but actually, the correct definition of a hypothesis is "A testable prediction about an experimental outcome".

2. Octet rule

The octet rule is about atoms tending to gain, lose, or share electrons to have 8 valence electrons. None of the given right - hand side options correctly define the octet rule. The option "electrons found in the orbital farthest from the nucleus" is the definition of valence electrons.

3. Law

A scientific law is a statement based on repeated experimental observations that describes some aspect of the universe. None of the given options correctly define a law. The option "sum of protons and neutrons in an atom" is the definition of mass number.

4. Period

A period in the periodic table is a horizontal row of elements. None of the given options correctly define a period. The option "a collection of elements forming a single column on the periodic table" is the definition of a group.

5. Atomic number

The atomic number is defined as the number of protons in an atom of an element. So "Atomic number" should be matched with "indicates the number of protons in an atom of an element".

6. Group

A group in the periodic table is a vertical column of elements. So "Group" should be matched with "a collection of elements forming a single column on the periodic table".

Correct Matches (after correcting the errors in the given options' associations):

• Atomic number - indicates the number of protons in an atom of an element
• Group - a collection of elements forming a single column on the periodic table

(Note: The original matches in the image are incorrect. The above are the correct matches based on standard scientific definitions.)

If we have to work with the given (incorrect) setup and assume possible typos:

• If we consider that "A testable prediction about an experimental outcome" is for "Hypothesis" (but the term is "Theory" here), "Theory" - A testable prediction about an experimental outcome (incorrect, but as per the given wrong setup)
• "Octet rule" - electrons found in the orbital farthest from the nucleus (incorrect, should be valence electrons)
• "Law" - sum of protons and neutrons in an atom (incorrect, should be mass number)
• "Period" - a collection of elements forming a single column on the periodic table (incorrect, should be group)
• "Atomic number" - indicates the number of protons in an atom of an element (correct)
• "Group" - a collection of elements forming a single column on the periodic table (correct)

The only correct match among the given terms and options (based on standard definitions) is:

Atomic number - indicates the number of protons in an atom of an element
Group - a collection of elements forming a single column on the periodic table

If we list the matches as per the given (wrong) connections and then correct:

Original wrong matches (to be corrected):

1. Theory - A testable prediction about an experimental outcome (should be Hypothesis)
2. Octet rule - a collection of elements forming a single column on the periodic table (should be Group)
3. Law - indicates the number of protons in an atom of an element (should be Atomic number)
4. Period - sum of protons and neutrons in an atom (should be Mass number)
5. Atomic number - an area in which the electrons of an atom orbit the nucleus (should be Orbital)
6. Group - electrons found in the orbital farthest from the nucleus (should be Valence electrons)

The correct matches (using standard definitions):

• Atomic number: indicates the number of protons in an atom of an element
• Group: a collection of elements forming a single column on the periodic table
• Period: a horizontal row of elements in the periodic table
• Law: a descriptive statement based on repeated experiments (e.g., Newton's laws)
• Theory: a well - supported explanation (e.g., atomic theory)
• Octet rule: atoms tend to gain/lose/share electrons to have 8 valence electrons

Since the problem asks to match with the given options (even if incorrect), and assuming a possible mix - up:

The only correct match from the given options (based on standard definitions) is:

Atomic number - indicates the number of protons in an atom of an element
Group - a collection of elements forming a single column on the periodic table

If we have to present the matches as per the problem's (incorrect) option list:

1. Theory - A testable prediction about an experimental outcome (incorrect, but as per given)
2. Octet rule - electrons found in the orbital farthest from the nucleus (incorrect, but as per given)
3. Law - sum of protons and neutrons in an atom (incorrect, but as per given)
4. Period - a collection of elements forming a single column on the periodic table (incorrect, but as per given)
5. Atomic number - indicates the number of protons in an atom of an element (correct)
6. Group - a collection of elements forming a single column on the periodic table (correct)

The answer with correct matches (ignoring the wrong original connections) is:

• Atomic number: indicates the number of protons in an atom of an element
• Group: a collection of elements forming a single column on the periodic table

If we follow the problem's (incorrect) matching lines and correct the associations:

Term	Correct Definition (from given options)
Group	a collection of elements forming a single column on the periodic table

These are the two correct matches from the given set of terms and options.
