All of the following are alkaline earth metals except … Radium Rubidium Strontium Magnesium 0% Non-Response Grid 0 of 20

Which of the following describes the characteristics of Group 18 elements? Most reactive non-metals Generally unreactive metals Never found in nature alone Have 8 valence electrons 0% Non-Response Grid 0 of 20

The most reactive non-metals are the… Alkali metals Halogens Transition Metals Noble gases 0% Non-Response Grid 0 of 20

The electron configuration for the Chloride ion is the same as what element? Ne S Ar Cl 0% Non-Response Grid 0 of 20

A positive ion is known as a … Anion Metal Cation Metalloid 0% Non-Response Grid 0 of 20

All of the following are factors that effect change in chemical properties except… Greater stability of half filled or completely filled sublevels The further away an electron is the less it feels the attraction to the nucleus The increase in atomic number causes the atom to grow in size A greater net positive charge results in a greater attraction of electrons to the nucleus The inner shell electrons cause the valence electrons to be repulsed 0% Non-Response Grid 0 of 20

As you travel from left to right across a period the electronegativity does what? Decreases Stays the same Increases 0% Non-Response Grid 0 of 20

Atomic size increases as you move down a group? True False Non-Response Grid 0 of 20

Which of the following would have the largest first ionization energy? Li Br 0% Non-Response Grid 0 of 20

The energy change that occurs when an electron is acquired by a neutral atom is known as what? Ionization energy Atomic size Electron affinity Charge 0% Non-Response Grid 0 of 20

Generally Ionization energies increase across a row, but there are some exceptions. Zn has a much higher first ionization energy than does Ga, Why? There is much more shielding of the nucleus in Gallium Zinc has a completely full 4s and 3d sublevels Zinc has a higher electronegativity than Gallium Zinc is a noble gas 0% Non-Response Grid 0 of 20
