The electronegativity of an element indicates the relative ability of its atoms to attract electrons in a chemical bond. According to the graph, as you move across a period on the periodic table, the atomic number
increases and the electonegativity increases
increases and the electonegativity decreases
decreases and the electonegativity increases
decreases and the electonegativity decreases
The ionization energy of an element indicates the energy it takes to remove an electron from the outermost level. As you move down a group in the periodic table, the ionization energy
decreases because the electron is farther from the nucleus
increases because the number of protons increases
decreases because the number of neutrons increases
increases because of the size of the atom increases
How many electrons does the element found in the second row and second column of the periodic table have available for bonding?
0
1
2
4
Why are the elements in column 17 of the periodic table have in the outer shell?
They have only one electron in their outer electron shells, so they frequently form singly charged positive ions
They have only two electrons in their outer shells, so they frequently bond with doubly charged negative ions.
They need only two electrons to complete their outer shells, so they easily bond with doubly charged positive ions.
They need only one electrons to complete their outer shells, so they easily bond with many types of elements
Which part of the atom has the least amount of mass?
first s orbital
neutrons
nucleus
protons
An atom
is much larger than its nucleus
is much lighter than its nucleus

An atom with the electron configuration 1s^2 2s^2 2p^4 is most likely
a metal that forms a positive ion

Robert Millikan dropped negatively charged oil droplets inside and outside an electric field to see
if oil drops fell faster than electrons
if oil drops fell faster than protons
how their rates of falling would be affected by a positively charges plate
if negatively charged particles were attracted to a positively charged plate
Albert Einstein proposed that electromagnetic energy is contained in
electrons
photons
quarks
