isotope
How many electrons, protons, and neutrons does the isotope below have?
14C
Electrons - 6 Protons - 6 Neutrons - 8
What type of bond and why?
Cu
Metallic, it is a metal by itself
How many electrons can the third shell of a Bohr model hold?
18
Is this an atom, an ion, or an isotope? Why?
21Na
It is an isotope because it has a different number of neutrons.
The atomic mass rounded is called the...
mass number
An atom has 14 protons, 14 neutrons, and 14 electrons. What is this an atom of?
Silicon
How do the electrons behave in an Ionic bond?
They are donated from a metal to a nonmetal
What are the two reasons why the Bohr model is "the best we have for now"?
-The model does not account for the movement of electrons
Is this an atom, an ion, or an isotope? Why?
Li+
It is an ion, it has a charge
If you change the number of electrons in an atom then you have a/an...
ion
Which is sodium more likely to bond with? Why?
Fluorine or Oxygen
Fluorine. Sodium has one electron to give and fluorine wants one electron, oxygen wants two electrons.
How do the electrons behave in a covalent bond?
They are shared between two nonmetals
How does the energy of an electron change in regards to its proximity to the nucleus?
The closer to the nucleus the more stable an electron is, the further an electron is from the nucleus the less stable it is
How many electrons, protons, and neutrons does the ion below have?
73Ge4+
If you change the number of protons in an atom you have a/an...
different element
Which is calcium more likely to bond with?
Oxygen or Bromine
It is more likely to bond with oxygen. Calcium has two electrons to donate, oxygen wants two electrons. Bromine only wants one electron.
