Atomic Radius
What is a radius?
A straight line from the center to the circumference of the circle or sphere
What is an ion?
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
What is Electronegativity?
Measure of the tendency of an atom to attract a bonding pair of electrons.
What does ionization energy mean.
It is the energy required to remove a electron from gaseous atom or ion.
What is a neutron?
a subatomic partical of about the same mass of a proton with out a charge
What is an energy level?
It is the fixed amount of energy that a system described by quantum mechanics.
What are two types of ions?
Cations and Anions
What atom has the highest electronegativity?
Florine
How does effective nuclear change affect ionization energy.
It makes electrons harder to remove and causes the ionization energy to increase.
Why is the mass on the periodic table a decimal?
To be precise.
Which energy level holds the electrons involved in reactions or bonds?
The last energy level.
How are cations and anions different?
Cations are positive and anions are negative.
How does effective nuclear charge effect electronegativity?
It's the pull the nucleus has on outer electrons.
which element has a higher ionization level?
ag or sn
ag
What is the formula to measure the mass on the periodic table?
Ram=E% isotope / 100
How do energy levels affect the size of an atom?
As the energy level increases the size must increase.
What is the octet rule?
a chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas.
What is electron shielding?
When the energy levels between the nucleus and valence electrons protect the outer shell of the atom.
which element has a lower ionization level?
O or Te
te
what does percent abundance mean?
It is the percentage of natural occurring isotopes in nature.
What is the smallest electrons on the periodic table?
Helium and Hydrogen are the smallest.
How do atoms satisfy the octet rule?
How does electron shielding effect the radius?
It tightens the atom to make it smaller and more compact.
How does the trend of ionization work across the periodic table?
It increases going to the right and increases going up.
What is the charge of a neutron?
it is neutral
