Match the trend on the periodic table to its description
Atomic radius
electronegativity
ionization energy
1. 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
3. a measure of the size of an atom
Atomic radius - 3. a measure of the size of an atom
Electronegativity - 1. a measure of how strongly atoms attract bonding electrons to themselves
Ionization energy - 2. the amount of energy required to remove an electron from an atom or molecule
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 trend on the periodic table to its description, you need to understand the periodic trends associated with each property. Here's how you can do it:
1. Atomic radius: The atomic radius is a measure of the size of an atom. It represents the distance from the nucleus to the outermost electron orbital. The trend for atomic radius is that it generally decreases across a period (from left to right) and increases down a group (from top to bottom) on the periodic table.
2. Electronegativity: Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves when they form chemical bonds. The trend for electronegativity is that it generally increases across a period (from left to right) and decreases down a group (from top to bottom) on the periodic table.
3. Ionization energy: Ionization energy is the amount of energy required to remove an electron from an atom or molecule. The trend for ionization energy is that it tends to increase across a period (from left to right) and decrease down a group (from top to bottom) on the periodic table.
Now that you know the definitions and trends for each property, you can match them to the descriptions:
1. Atomic radius: Description 3 - a measure of the size of an atom
2. Electronegativity: Description 1 - a measure of how strongly atoms attract bonding electrons to themselves
3. Ionization energy: Description 2 - the amount of energy required to remove an electron from an atom or molecule
