Atom Makeup
This sub atomic particle is positive and located in the nucleus.
What is a proton?
This term refers to the rows on a periodic table and represents the number of electron shells and atom has.
What are periods?
An atom has a mass of 35 and an atomic number of 17. How many neutrons would it have?
18
The atomic theory states that these are the smallest units of matter.
What are atoms?
The numbers of these sub atomic particles may vary depending on an atom's charge.
What are electrons?
This term refers to the columns on the periodic table, arranged by valence electrons.
What are groups or families?
How many protons are in Iron-56?
26
This was one of the first theories of matter, proposed by JJ Dalton which depicted atoms as "balls" of matter that were indivisible.
These are the two regions of an atom.
What are the nucleus and electron cloud?
These elements are said to be found on a "step."
What are the metalloids.
What is the difference between carbon-12 and carbon-14? (Hint: Be very specific.)
Carbon-14 has 8 electrons and Carbon-12 has 6.
This model of the atom is said to be the most accurate to the atom's "true" construction.
What is the electron cloud model?
This part of the atom contributes the majority of the atom's mass and is considered the densest portion.
What is the nucleus?
These two groups of elements are often removed from the table and placed below.
What are the lanthanides and actinides?
If an element has a mass of 223 and 136 neutrons, which element is it?
Francium.
This model shows the electrons in orbits around a nucleus of positive charge, and can be helpful when studying electron configurations and bonding behaviors.
What is the Bohr model?
These sub atomic particles are made up of up and down quarks and gluons.
What are protons and neutrons?
This family of elements belongs to period one, and they are highly reactive.
What are the alkali metals?
How many electrons would an atom of 55Mn7+ have?
18.
This ancient Greek philosopher is often credited with first depicting the atoms with the word atomos or "indivisible."
