Periodic Table
What is the periodic table?
Is a chart of elements arranged into rows and columns according to their physical and chemical properties.
How is the periodic table used to predict the properties of an element?
The Periodic Table can predict the properties of new elements because it organizes the elements according to their atomic numbers.
Which part of the atom is shared, gained, or lost when forming a chemical bond?
A. electron B. Nuetron C. Nucleus D. Proton
A. Electron
What is a group?
A group is a column on the periodic table. The groups are numbered 1-18.
What is a chemical bond?
It is a force that holds two or more atoms together.
Why do atoms gain, lose, or share electrons?
When they bond with other atoms.
What is a period?
They are rows on the perioidic table.
What is a valence electron?
It is an outermost electron of an atom that participates in chemical bonding.
How many valence electrons does an atom of oxygen have?
6 valence electrons
How are elements arranged on the periodic table?
A table in which the chemical elements are arranged in order of increasing atomic number.
What is an electron dot diagram?
A model that represents valence electrons is an atom as dots around the element's chemical symbol.
How many valence electrons does sulfur have?
6 Valence electrons
What does the decimal number in an element key represent?
A. Atomic Mass B. Atomic Number C. Chemical Symbol
D. State of matter
A. Atomic Mass
Where are metals, nonmetals, and metalloids, on the periodic table?
Metals are located on the left of the periodic table, and nonmetals are located on the upper right. The metalloids are located to the right of the post-transition metals and to the left of the non-metals.
How is the periodic table organized?
Elements are arranged from left to right and top to bottom in order of increasing atomic number.
