Protons
What does the proton value tell us about an atom.
Its name.
The amount of protons an atom has is directly corelated to its name.
What is the charge of a neutron?
Neutral ( )
What is the weight of 1 electron?
0 amu
Define ionization energy.
The amount of energy required to remove an electron from an atom.
Define Electronegativity.
How many protons does carbon (C) have?
6
How much does 1 neutron weigh?
1 (amu)
What is the charge of an electron?
Negative (-)
Is Lithium's ionization energy high, low, or zero.
Low
Due to lithium only having one valence electron on its outer most shell, the energy required to take that electron would be very low.
Is Lithium's electronegativity high, low, or zero
Low
Due to Lithium only having 1 electron on its outer most shell, the desire for it to gain more electrons is very low.
How much does 1 proton weigh?
1 (amu)
How many neutrons does nitrogen - 15 have?
8
Nitrogen has 7 protons, so 15 - 7 = 8 neutrons
How many shells would aluminum (Al) have?
3
It is on the third row, so it would have enough electrons to support 3 shells.
Is Fluorine's ionization energy high, low, or zero.
High
Fluorine is one electron away from a full shell of electrons and so the energy required to disturb that stability would need to be high.
Is Fluorine's electronegavity high, low, or zero.
Extremely high
Because fluorine is one electron away from having a full shell, its desire for more electrons would be high.
What is the charge of a proton?
Positive (+)
What is the atomic weight be for chlorine (Cl) if its natural abundance is approximately 75% chlorine - 35 and 25% chlorine - 37?
35.5
((75 x 35) + (25 x 37)) / 100 = 35.5
What would the charge of a fluorine atom be if it had 10 electrons?
-1
Fluorine has 9 positive protons and so if it has 10 negative electrons then 9 - 10 = -1
And ion is an atom with uneven amounts of protons and electrons resulting in the atom acquiring a charge.
How many total electrons would an atom on the second row of the periodic table need to have a full outer shell?
8
What element has 17 protons
Chlorine (Cl)
Which isotope below has the most neutrons?
A. Neon - 21
B. Fluorine - 21
C. Sodium - 22
D. Magnesium - 23
B. Fluorine - 21
Fluorine has 9 protons, 9 - 21 = 12
Every other isotope listed has 11 or fewer neutrons.
Explain static electivity using electrons
When an object acquires a higher concentration of electrons then it will become negatively charged, when that coagulation of negatives moves to an object that is neutral or positive, a static shock occurs.
Is Neon's ionization energy high, low, or zero.
High
Neon has a full shell of electrons and so the energy required to disturb that stability would need to be very high.
Is Neon's electronegavity high, low, or zero.
Zero
Because Neon has a full shell of electrons, it has no desire to gain any more.
