What are energy levels?
What is electrons in the regions around the nucleus
100
In a covalent bond, atoms ____________________ electrons.
What is share
100
In ionic bons, atoms ___________________________ electrons
What is give or take
200
This subatomic particle has a neutral charge and is found in the nucleus
What is a neutron
200
If a oxygen atom has eight protons it also has ________________ electrons
What is eight
200
How many electrons can fit on the first, second, and third energy levels?
What is 2, 8, and 8,
200
One reason atoms can bond covalently is: (HINT: look at question 2 on your 4.4 lesson)
What is 1) there is enough room in the outer energy level to share an electron 2) the electrons and protons are attracted to each other.
200
What is an ion and how is it formed?
What is an ion is a an atom that has lost or gained an electron. It is formed when an electron is taken or gained from another atom.
300
This subatomic particle has a negative charge and is found in the orbital around the nucleus
What is electron
300
Rows in the periodic table are called ____________________.
What are periods
300
True or False: There can be 9 electrons in the second energy level.
What is false
300
True/False: It is possible to have double covalent bond.
What is true. Oxygen forms a double bond
300
In the process of ionic bonding, ions come together because
What is Positive and negative ions attract
400
Atoms have an equal number of what two subatomic particles?
What is protons and electrons
400
Columns in the periodic table are called ____________________.
What are families or groups
400
The electrons on the outermost energy level are called:
What is valence electrons
400
Two hydrogen atoms can bond covalently together. Why can't a third hydrogen atom bond as well?
What is the outer energy level is full and the protons and electrons are not as attracted to each other.
400
When an atom loses an electron, it forms a ______________ ion
What is negative
500
The electrons on the outermost energy level of an atom are called ____________________ electrons.
What are valence
500
Which three subatomic particles are attracted to each other and why?
What is protons and electrons. Protons have a positive charge and electrons have a negative charge. Positives and negatives attract to each other.
500
Sodium has 11 protons and 11 electrons. The electrons fill the energy levels in Sodium like this:
What is 2 in the first, and 8 in the second, 1 in the third
500
Name one example of a covalent bond.
What is (hydrogen gas, water, methane, etc.)
500
When an atom gains an electron, it forms a ______________ ion.
What is positive
