A cyclotron is a device that can accelerate charged particles to very high velocities, and can be used to generate protons with radiative wavelengths that can kill cancer cells. What is the de Broglie wavelength of a proton (mass 1.673 x 10-27 kg) that has been accelerated to a velocity of 126 m/s? - ANSWER-3.14 x 10-9 m wavelength= h/mv

• 6.626 * 10^-34 ) / ( 1.673 x 10-27 kg * 126 m/s )= 3.14 x 10-9

Sort the following atoms in order of increasing covalent radius:

Mg, Na, Rb, Be. - ANSWER-Be < Mg < Na < Rb

Electron Affinity is

• the energy change when an electron is added to a gaseous

atom to form an anion

• half the distance between the nuclei of two identical atoms

connected by a covalent bond

• the tendency of an atom to attract electrons towards itself in a

covalent bond

• the energy required to remove the most loosely bound

electron from a gaseous atom to form a cation - ANSWER-The energy change when an electron is added to a gaseous atom to form an anion

Trends in the periodic properties of the size of atoms, ionization energy, and electron affinity

• Cannot be used to make even general predictions based on the

position of the elements in the periodic table.

• Occur because the elements in each group on the periodic

table have similar numbers of protons

• Are always correctly predicted based solely on the position of

the elements in the periodic table 2 / 3

• Should be thought of as general guidelines that are useful to

predict chemical behavior, but there are many deviations from the general trends. - ANSWER-Should be thought of as general guidelines that are useful to predict chemical behavior, but there are many deviations from the general trends.

If an atom has an energetically unfavorable electron affinity and a favorable ionization energy, it is most likely to - ANSWER- lose an electron to form a cation
