Know the reference table
This represents the number of protons and the nuclear charge of any atom
What is atomic Number?
As you move down a group, the atomic radius of elements does this.
What is it increases?
This group on the far right of the table has eight valence electrons and is famously unreactive.
What are the Noble Gases?
If nitrogen has an atomic number of 7, this is its ground-state electron configuration.
What is 2-5?
This type of bond forms when a metal transfers one or more electrons to a nonmetal.
What is an ionic bond?
The mass number of an element minus its atomic number equals this subatomic particle.
What is a neutron?
This term describes an atom's ability to attract electrons in a chemical bond. It increases as you move from left to right across a period.
What is electronegativity?
Group 1 elements are highly reactive metals collectively known as these.
What are the Alkali Metals?
Electrons in the outermost shell are the most important for chemical bonding and are called these.
What are valence electrons?
This type of bond involves the sharing of electrons between two or more nonmetals.
What is a covalent bond?
This specific reference table gives the list of polyatomic ions.
What is Table E?
Nonmetals on the right side of the staircase generally have this type of charge when they form an ion.
What is negative?
Group 17 consists of highly reactive nonmetals collectively known as these.
What are the Halogens?
When an electron absorbs energy and jumps to a higher, unstable principal energy level, the atom is in this state.
What is the excited state?
This term describes a solid substance that contains a sea of mobile, decentralized electrons, allowing it to conduct electricity.
What is a metallic bond?
This term describes a row of elements that all have the same number of principal energy levels.
What is a period?
Metals on the left side of the periodic table generally do this with their electrons to form positive ions.
What is they lose electrons?
Elements that touch the "staircase" separating metals from nonmetals, exhibiting properties of both, are called these.
What are metalloids?
If an electron configuration on the reference table reads 2-7-1, this element is considered to be in this unique condition.
What is the excited state?
This molecular property causes asymmetrical molecules like water to have partial positive and negative charges.
What is polarity?
According to Table S, this element has the highest first ionization energy on the entire periodic table.
What is Helium?
An atom of Oxygen has a smaller atomic radius than an atom of Carbon because the Oxygen atom has a greater number of this specific feature.
What is valence electrons?
This is the phase of matter, at STP, of the Group 17 element that possesses the greatest atomic radius.
What is a solid?
When a ground-state atom of Lithium emits light in a bright-line spectrum, its electrons are undergoing this specific movement.
What is moving from a higher energy level to a lower energy level?
Although a molecule of carbon dioxide (\(CO_{2}\)) contains polar bonds, the overall molecule is classified as nonpolar due to this specific structural feature.
What is its symmetrical shape?
