1)
what is a column called in the periodic table and what do the elements in each column have in common?
a) period; the same atomic mass
b) group; the same number of electrons
c) period; the same number of atomic orbitals
d) group; the same number of valence electrons
2)
the alkali metals, found in group 1 of the periodic table, are very reactive metals that do not occur freely in nature. these metals have only one electron in their outer shell. therefore, they readily lose that one electron to form ionic bonds with other elements. sodium (na) is an alkali metal that bonds with chlorine (cl), a halogen, to form table salt (nacl). based on what the periodic table can tell you about these two elements, explain how and why they bond to form nacl.
a) na and cl share electrons to form an ionic bond.
b) na and cl share electrons to form a covalent bond.
c) na and cl transfer electrons to form ions and create an ionic bond.
d) na and cl transfer electrons to form ions and create a covalent bond.
