Match the trend on the periodic table to its description.
Column A
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
Column B
A. Atomic radius
B. ionization energy
C. Electronegativity
1. C. Electronegativity
2. B. Ionization energy
3. A. Atomic radius
Matching the trends on the periodic table to their descriptions:
1. Column B - C. Electronegativity (a measure of how strongly atoms attract bonding electrons to themselves)
2. Column B - B. Ionization energy (the amount of energy required to remove an electron from an atom or molecule)
3. Column A - A. Atomic radius (a measure of the size of an atom)
To match the trends on the periodic table to their descriptions, let's break down each term and understand its meaning.
Column A:
1. Electronegativity - This term refers to a measure of how strongly atoms attract bonding electrons to themselves. It helps us understand the tendency of an atom to attract and share electrons in a chemical bond.
2. Ionization energy - This term represents the amount of energy required to remove an electron from an atom or molecule. It is an indication of how tightly an atom holds its electrons.
3. Atomic radius - This term measures the size of an atom, specifically the distance between the nucleus and the outermost electron shell. It provides insights into the size of the atom and its electron cloud.
Now, let's match the trends in Column B to their corresponding descriptions:
A. Atomic radius - The correct match for "a measure of the size of an atom" is atomic radius. Atomic radius increases as you move down a group or column on the periodic table. This means that atoms become larger as you progress from top to bottom within a particular group.
B. Ionization energy - The correct match for "the amount of energy required to remove an electron from an atom or molecule" is ionization energy. Ionization energy generally increases as you move from left to right across a period on the periodic table. It means that atoms become more difficult to ionize (remove an electron) as you move from left to right.
C. Electronegativity - The correct match for "a measure of how strongly atoms attract bonding electrons to themselves" is electronegativity. Electronegativity generally increases as you move from left to right across a period on the periodic table. It means that atoms become more effective at attracting and holding onto electrons as you move from left to right.
So, the correct matches are:
1. C - Electronegativity
2. B - Ionization energy
3. A - Atomic radius
