Periodic trends review practice - reaction tendencies

Multiple Choice

What is ionization energy?

• Energy needed to destroy an atom
• Energy required to remove an electron
• Energy needed to split an electron
• Energy required to add an electron

Multiple Choice

As you look from left to right across a period, ionization energy and electronegativity both

• increase

• decrease

Multiple Choice

As you look down a group, ionization energy and electronegativity

• increases

• decreases

Multiple Choice

Ionization energy decreases down a group because

• There are more protons pulling on the electrons

• There are more energy levels (more distance and SE)

Multiple Choice

Electronegativity is...

• how good an atom is at attracting electrons
• the ability of an atom to lose electrons
• the energy required to remove an electron from a specific atom
• how easy it is to make friends. 

Multiple Choice

Electronegativity increases across a period because

• More protons can better attract electrons

• more energy levels can better attract electrons

Multiple Choice

EN decreases down a group

• more protons

• more energy levels increases distance between protons and electrons and more shielding effect
