Fire,Water,Earth, Air | 4 Fundamental Elements of Aristole |
1.All Matter is Composed of indivisible particles called atoms 2.Atoms of a given element posses unique properties 3.Atoms of a given element possess unique properties and individual masses 4.Atoms combine in simple whole number ratios to form compound | 5 different principles of Daltons Atomic Theory |
opposites attract, even across distances like charges repel even across distances positives charges neutralizes negative charges | Benjamin Franklin 3 principles that describe the behavior of electric charge |
The # Protons present in a atom differentiattes element atoms | What fundamentally identifies an atom as uniquely belonging to a particular element |
electrically Neutral | atoms with the same # of protons |
By definition an ion has a different numbers of electrons and protons. | What is the relationship between the number of protons and the number of electrons in an ion? |
The atom will be found as an ion possessing a negative charge. | What is the consequence in terms of electric charge for an atom that has more electrons than protons? |
The atom will be found as an ion possessing a positive charge. | How about if there are more protons than electrons? |
The atomic number represents the number of protons in the atom and specifies thye element type. Mass | What’s the difference between mass number and atomic number? |
which has lost or gained one or more electrons, making it positively or negatively charged. | What is an ion? |
The number of Protons or the positive charge held in the nucleus. | What quantity is represented by the sequential numbers on the periodic table? |
An atom having the same atomic number but differing mass number from | What is an isotope? |
An s orbital has the fewest electrons with only one orbital (2 electrons) it is spherical in shape. | What is the shape of the subshell that contains the fewest electrons? |
Electrons present in the outer most principle energy level. Specifically electrons present in the s and p | By definition what are valence electrons? |
is based on assigning the ass of a single carbon -12 atom | The atomic mass scale |
the fraction of the total # of element atoms present taht is composed of a specific isotope | What is Fractional Abundance |
