Subatomic Particles
These are the subatomic particles that make up an atom. (Mikayla)
What are protons, neutrons, and electrons?
The maximum number of electrons that are allowed on the 1st ring of an atom. (Naomi)
What is 2?
This is the number of MAIN groups of elements on the periodic table. (Ananth)
What is 8?
This is the group with the lowest electronegativity on the Periodic Table. (Sophie)
What is group 8, or the noble gases?
These 2 numerical characteristics are displayed on the periodic table for each element. (Sam)
What are atomic number and atomic mass?
This is represented by the atomic number of an element. (Sophie)
What are the numbers of protons and electrons?
These are represented by dots on a Lewis Dot diagram. (Sophie)
What are valence electrons?
This is the name for a row (going left to right) on the Periodic Table. (Sam)
What is a period?
These are the directions in which atomic radius increases. (Sam)
What are down and to the left?
Does Y or Rn come first on the periodic table? (Ananth)
Y (#39!)
This is the name for the electrons in the outer energy level of an atom. (Mikayla)
What are valence electrons?
This is the maximum number of electrons that can be on an energy level, after the first level. (Ms. Kane)
What is 8?
This is the group where Te is located. (Connor R)
What is group 6?
These 2 periodic trends increase as you progress to
the right in a period. (Naomi)
What are ionization energy and electronegativity?
This is the number of protons that are in an atom with atomic number 25. (Connor R)
The number of neutrons in an atom of Cesium if it has an Atomic Mass of 132.91 and an Atomic Number of 55. (Pierre)
What is 78?
(133-55)
This is where the electrons are shown in the Bohr Model. (Sophie)
What is on energy levels outside of the atom?
This is what happens to the number of valence electrons as you go from left to right. (Pierre)
What is increases?
The element with more electronegativity - Te or N?
What is N? (Te is closer right but much further down, so its radius is way bigger)
This is the group that has the lowest ionization energy. (Sam)
This is how to find the number of neutrons in an atom. (Sophie)
What is subtracting the atomic number from the mass?
(Mass - atomic number)
Draw a Lewis Dot diagram for Helium, in the 8th group. (Pierre)
He with 2 dots around it
This is what makes the noble gases unique. (Ms. Kane)
This is the reason that atomic radius DECREASES going left to right on the Periodic Table. (Sophie)
What is increasing protons and neutrons means the nucleus pulls the electrons closer?
Draw a Bohr model of an atom of Boron (B). (Pierre)
Nucleus: 5P, 6N
2 rings: 2e, then 3e
