Atomic Structure
This subatomic particle has a negative charge.
What is an electron?
This term describes a horizontal row on the periodic table.
What is a period?
This type of bond involves the sharing of electrons.
What is a covalent bond?
This number on the periodic table tells you how many protons an atom has.
What is the atomic number?
Radioactive decay involves changes in this part of an atom.
What is the nucleus?
This part of the atom contains protons and neutrons.
What is the nucleus?
This term describes a vertical column on the periodic table.
What is a group or family?
This type of bond usually forms between a metal and a nonmetal.
What is an ionic bond?
What is the atomic number?
What is number of protons?
Atoms of the same element with different numbers of neutrons are called this.
What are isotopes?
An atom has 11 protons and 12 neutrons. What is its mass number?
What is 23?
Elements in this group are called boron family.
What is Group 13?
In ionic bonding, electrons are transferred. Which type of atom typically loses electrons: a metal or a nonmetal?
What is a metal?
Sodium loses one electron. What charge does its ion have?
What is +1, or Na⁺?
Radioactive decay is classified as a chemical change or a nuclear change?
What is a nuclear change?
A neutral atom has 15 protons. How many electrons does it have, and why?
What are 15 electrons, because a neutral atom has equal numbers of protons and electrons?
An element is in Group 17 and Period 3. Identify the element.
What is chlorine?
Determine the type of bond expected between two oxygen atoms and explain why.
What is a covalent bond? Oxygen atoms are nonmetals that share electrons.
A student says carbon and oxygen form an ionic bond because carbon is a metal. Identify the error and correct the claim.
What is covalent bond because carbon is a nonmetal?
Which type of nuclear radiation consists of a helium nucleus containing two protons and two neutrons?
What is alpha decay/radiation (an alpha particle)?
Two atoms have 8 protons each, but one has 8 neutrons and the other has 10. Explain how they are related.
What are isotopes of oxygen? They are the same element but have different numbers of neutrons.
Elements in the same group often have similar chemical properties. Explain why.
What is that they generally have the same number of valence electrons?
A student says that water (H₂O) contains ionic bonds because hydrogen and oxygen both need electrons. Is the student correct? Explain why or why not.
What is no? Water contains covalent bonds because hydrogen and oxygen share electrons.
An atom has 17 protons, 18 neutrons, and 17 electrons. What is its atomic number and mass number?
What is 17 (an) & 35 (mn)?
What is the name of the process in which an unstable atomic nucleus releases radiation?
What is radioactive decay?
