EMS (Electromagnetic spectrum)
High energy
Neutrons and protons are found in the nucleus. What other particle makes up an atom and is found outside of the nucleus?
Electron
What is the trend for ionization as you move from left to right on the periodic table?
Ionization energy increases
Moving left to right on the periodic table, what trend do we observe with the radius of atoms?
Atomic radius decreases
What is the trend for electronegativity as you move from left to right on the periodic table?
Electronegativity increases
Which color of visible light has the highest energy?
Blue/Violet
An isotope of Silicon has 14 protons, 16 neutrons, and a mass of 30. If the isotope has a neutral charge, how many electrons will it have?
14
What is the trend for ionization as you move from top to bottom on the periodic table?
Ionization energy decreases
Moving from top to bottom on the periodic table, what trend do we observe with the radius of atoms?
Atomic radius increases
What is the trend for electronegativity as you move from top to bottom on the periodic table?
Electronegativity decreases
Which color of light has the lowest energy?
Red
Magnesium would have electrons found in the first _____ energy levels?
Which of these atoms would have a larger ionization energy: Silicon or Chlorine?
Chlorine
Put these atoms in terms of INCREASING atomic radius: Tin, Iodine, Strontium, Rubidium.
Iodine, Tin, Strontium, Rubidium.
Which of these atoms would be the lease electronegative: Potassium or Bromine?
Potassium
What is the name for a "particle" of light?
Photon
Further away
Which of these atoms would have a larger ionization energy: Calcium or Barium?
Calcium
Which of these would have the largest radius: Mg or Mg+2
Mg
Put these atoms in terms of DECREASING electronegativity: Nitrogen, Arsenic, Phosphorus, antimony
Nitrogen, Phosphorus, Arsenic, Antimony
Using the terms ground state and excited state, describe how an electron emits a photon of light so that we can see visible color.
An electron receives energy and moves to its excited state. When the electron returns to its ground state, it will emit a photon of light.
Sulfur has how many electrons in its outermost shell? (Or, in other words, how many valence electrons does it have?)
six
What is the relationship between atomic radius and ionization energy?
As atomic radius increases, ionization energy decreases.
OR
As atomic radius decreases, ionization energy increases.
Why does fluorine have a smaller atomic radius than oxygen?
Both atoms have electrons in the 2nd energy level but fluorine has 9 protons and oxygen has 8. Since fluorine has more positively charged protons in its nucleus it has a stronger pull on the electrons in the 2nd energy level.
What is the relationship between atomic radius and electronegativity?
As atomic radius decreases, electronegativity increases.
