What is the atomic number?
the amount of protons in an element
the amount of neutrons in an element
the amount of both neutrons and protons in an element
the amount of electrons in the 2nd shell
What is electronegativity?
how negative a particular electron is
the theory stating that the more electrons an atom has, the more negative it is
a periodic trend where it increases from up to down
the atom's affinity for electrons
What is an isotope
a form of the element with differing amounts of electrons
a form of the element with differing amounts of neutrons
a form of the element with different bonding structure
a form of the element with different amount of valence electrons
Select the characteristics belonging to ionic bonds
elements "steal" electrons in bond
elements share electrons in bond
bonds are between a metal and a nonmetal
bonds are between two nonmetals
What is atomic mass?
protons and neutrons
only nuetrons
only protons
protons and electrons
What is false about covalent bonds?
Electrons are shared between atoms
Bond is between two nonmetals
Can be polar or non polar
Very rare in nature
What is a cation? What is an anion?
they are both negatively charged ions
a cation is a positively charged ion, anions are negatively charged
a cation is negatively charged ion, anions are positively charged
they are both positively charged ions
