Match the trend on the periodic table to its description
Column A
1.
a measure of how strongly atoms attract bonding electrons to themselves:
a measure of how strongly atoms attract bonding electrons to themselves
2.
the amount of energy required to remove an electron from an atom or molecule:
the amount of energy required to remove an electron from an atom or molecule
3.
a measure of the size of an atom:
a measure of the size of an atom
Column B
a.ionization energy
b.electronegativity
c.atomic radius
1. b. electronegativity
2. a. ionization energy
3. c. atomic radius
Column A:
1. b. electronegativity
2. a. ionization energy
3. c. atomic radius
Therefore, the correct matching of the trends on the periodic table is:
1. Electronegativity - a measure of how strongly atoms attract bonding electrons to themselves.
2. Ionization energy - the amount of energy required to remove an electron from an atom or molecule.
3. Atomic radius - a measure of the size of an atom.
To match the trends on the periodic table to their descriptions, we need to understand the concepts mentioned in Column A and their corresponding terms in Column B. Let's go through each one:
1. The description "a measure of how strongly atoms attract bonding electrons to themselves" refers to electronegativity. Electronegativity is the tendency of an atom to attract electrons towards itself when forming a chemical bond.
2. The description "the amount of energy required to remove an electron from an atom or molecule" corresponds to ionization energy. Ionization energy is the energy needed to remove an electron from an atom or ion in its ground state, forming a positively charged ion.
3. The description "a measure of the size of an atom" represents atomic radius. Atomic radius refers to the distance between the nucleus of an atom and the outermost occupied electron shell, which determines the size of an atom.
Matching the descriptions to their respective terms, we have:
1. Electronegativity - a measure of how strongly atoms attract bonding electrons to themselves.
2. Ionization energy - the amount of energy required to remove an electron from an atom or molecule.
3. Atomic radius - a measure of the size of an atom.
By understanding these concepts and their definitions, you can match the trends on the periodic table to their corresponding descriptions.
