No charge
A negative charge
A positive and negative charge
A positive charge
Neutrons are in the nucleus of the atom. A neutron has...
A positive charge
No charge
A negative charge
Twice as much positive charge as a proton
An electron is in a region outside the nucleus. An electron...
Is larger than a proton and has no charge
Has less mass than a proton and has a negative charge
Is smaller than a proton and has no charge
Has a positive charge
A hydrogen atom is made up of one proton and one electron. The proton and electron stay near each other because...
Positive and negative charges repel
Positive and positive charges repel
Positive and negative charges attract
Two negatives make a positive
The atomic number of an atom is...
The mass of the atom
The number of protons added to the number of neutrons
The number of protons
Negatively charged
The atoms of the same element can have different isotopes. An isotope of an atom...
Is an atom with a different number of protons
Is an atom with a different number of neutrons
Is an atom with a different number of electrons
Has a different atomic number
The atomic mass of an element is...
The average mass of all the isotopes of the element
A measure of the density of that element
The mass of the most common isotope of that element
The number of protons and electrons in the atoms of the element
An element and an atom are different but related because...
A particular element is made up of many different types of atoms
A molecule is the same as an atom
An element is made up of all the same type of atom
An element is smaller than an atom
The periodic table shows that a carbon atom has six protons. This means that a carbon atom also has
Six electrons
Six neutrons
More protons than electrons
An atomic mass that equals six
The atomic number of nitrogen is 7. The atomic mass is 14.01. This means that
All nitrogen atoms have exactly 7 neutrons
A small percentage of nitrogen atoms have fewer than 7 neutrons
A small percentage of nitrogen atoms have more than 7 neutrons
Some nitrogen atoms have fewer than 7 electrons
Electrons are in regions around the nucleus called energy levels. The first energy level
Is furthest from the nucleus
Is closest to the nucleus
Holds the most elecrons
Needs more than two electrons to fill it up
Neon has 10 protons and 10 electrons. The electrons fill the energy levels in Neon like this:
2 in the first, 2 in the second, and 6 in the third
4 in the first, 4 in the second, and 2 in the third
2 in the first, 4 in the second, and 4 in the third
2 in the first, and 8 in the second
The atoms in a column of the periodic table all have...
The same abbreviation
The same number of energy levels
The same number of electrons
The same number of electrons in the outer energy level
In the process of covalent bonding, atoms share electrons. This means that...
Electrons from each atom are attracted to the nucleus of both atoms
Protons and neutrons attract
Atoms lose electrons and become ions
Atoms gain electrons and become ions
In the process of ionic bonding
Both atoms gain electrons
One atom gains one or more electrons and the other loses the same number
Atoms switch protons
Both atoms lose electrons
In the process of ionic bonding, ions come together because...
Opposite charges repelt
Positive and negative ions attract
Salt is magnetic
Like charges attract each other
In a Lewis dot diagram, the electrons shown...
Are in the innermost energy level
Always equal the number of protons
Are in the outermost energy level
Always add up to an even number

True
False
It is possible to have a double covalent bond.
True
False
