in your textbook, read about chemical bonds and formation of ions.
use each of the terms below just once to complete the passage.
chemical bond electrons energy level ions noble gases
nucleus octet pseudo - noble gas formations valence
the force that holds two atoms together is called a(n) (1)
such an attachment may form by the attraction of the positively charged
(2) of one atom for the negatively charged
(3) of another atom, or by the attraction of charged atoms, which are called
(4). the attractions may also involve
(5) electrons, which are the electrons in the outermost
(6). the (7) are a family of elements that have very little
tendency to react. most of these elements have a set of eight outermost electrons, which is called a stable
(8). the relatively stable electron structures developed by loss of electrons in
certain elements of groups 3, 4, 13, and 14 are called (9)

Explanation:

1. A chemical bond is the force that holds atoms together.
2. The nucleus is positively charged.
3. Electrons are negatively charged.
4. Ions are charged atoms.
5. Valence electrons are in the outermost energy level.
6. Energy level is related to electron location.
7. Noble gases have low reactivity.
8. An octet is a set of eight outermost electrons.
9. Pseudo - noble gas formations are stable electron structures for some elements.

Answer:

1. chemical bond
2. nucleus
3. electrons
4. ions
5. valence
6. energy level
7. noble gases
8. octet
9. pseudo - noble gas formations
