bonding, structures and the properties of matter Flashcards
how are ions made
when electrons are transferred
how do metals become ions
loosing electrons
how do non-metals become ions
gaining electrons
whats the connection between number of electrons lost/gained and the charge on the ion
number of electrons lost/gained = charge on the ion
what groups are most likely to form an ion
1,2,6,7
why are group 1, 2 and 6,7 most likely to form ions
group 1,2 = metals
group 6,7 = non-metals
what happens to a sodium atom when it loses 1 electron
it forms an ion Na¯
Na → Na+ + e¯
what happens to magnesium atom when it loses 2 electrons to form an ion
it forms a Mg²+
predict the charges of the ions formed by theses three elements
1)Bromine 2)Calcium 3) potassium
1) Br¯
2) Ca²+
3) K+
why do simple ions want to have noble gas electronic structure
they have full outer shells of electrons and are very stable
what is ionic bonding
the process by which a metal and non-metal react together, they are attracted together by electrostatic forces
