Most of the mass of the atom comes from these two particles located in the nucleus.
What are protons and neutrons?
This charged particle forms when an atom gains or loses an electron.
What is an "ion?"
You have a sample that is brittle and a poor conductor of heat and electricity. The substance tends to gain electrons to achieve a full octet. Is this element a metal, nonmetal, or metalloid?
What is a nonmetals?
On the periodic table, the vertical columns are called _______________ but the horizontal rows are called _______________.
What are "groups/families" and "periods."
How much an atom wants its electrons is described by this term.
What is "electronegativity?"
Use the periodic table to figure out how many protons, neutrons, and electrons are in Potassium (K).
What are protons & electrons = 19 Neutrons = 20
Metals tend to form this type of ion and nonmetals tend to form this type of ion.
What are "cations" and "anions?"
Malleable, ductile, shiny and conductive are properties of this category of elements.
What is a metal?
This most reactive group of soft, silvery metals can easily give away their atoms’ one valence electron and form 1+ cations.
What are the "Alkali Metals?"
This is how the atomic number changes across a period.
What is "increase" by one?
These two subatomic particles have opposite charges and keep the atom "neutral."
What are "electrons" and "protons?"
For this reason, the Noble Gases do not usually react with any other elements?
What is "they have full octets ( valence shells)?
Located between the Alkaline-Earth Metals and the Boron family, these 10 groups of elements do not have individual names but contain valuable metals with varying ionic charges.
What are the "Transition Metals?"
This very reactive group of nonmetals only need one valence electron to complete their outer shell and form 1- anions.
What are the "Halogens?"
Describe the trend of Atomic Radius (the size of an atom) down a group and across a period?
What is ...increases down a group but decreases across a period?
This number is used to identify an element and is equal to the number of protons in its nucleus.
What is the "atomic number?"
Which family creates ions with a charge of 3+?
What is the "Boron Family or Group 13?"
Jacob has an element that is a shiny, brittle solid that conducts electricity; it doesn’t conduct electricity as well as copper. Is this element a metal, metalloid, or a nonmetal?
What is a metalloid?
The properties of elements in a group are similar because the atoms have the same number of these particles in their outer energy level.
What are the "valence electrons?"
Describe the periodic trends of Ionization Energy (the energy required to “remove an electron from an atom,)" down a group and across a period.
What is... decreases down a group but increases across a period?
This element does not belong to any one group on the periodic table because it is has properties of both metals and nonmetals.
What is "Hydrogen?"
The charge and type of ion usually formed by the Alkaline-Earth Metals is?
What is a "2+ cation?"
How do the metallic properties of the elements change from left-to-right across a period?
What is "decrease?"
Which group, or family, on the Periodic Table has six (6) valance electrons?
What is the "Oxygen Family or Group 16?"
Elements are placed in a period because they have this in common.
What is "the same number of energy levels / electron shells."
