Positively charged particles that are found in an atom's nucleus.
How do ionic bonds form? Please use NaCL (common table salt) as your example.
Na loses an electron and gains a positive charge. Cl gains Na's electron and becomes negative. The ions now attract like magnets.
Atoms of the same element that differ in the number of neutrons that they contain in their nucleus are known as _.
Isotopes
What will Carbon's Group Number tell you?
That it has four valence electrons in its outermost shell.
What are molecules?
Chemicals made when atoms share their valence electrons. Water is an example of a molecule.
How many covalent bonds are there in a molecule of methane (CH4)?
Methane has four covalent bonds.
Which of the following would be a radioactive isotope? Explain why. Carbon-12, Carbon-13, Carbon-14.
Carbon-14 is the radioactive isotope of carbon. It's radioactive because it has more neutrons than protons.
What will Carbon's Period Number tell you?
That it has two electron shells.
How many electron shells does a carbon atom have?
In a carbon atom, there are two shells for the electrons to "live" in.
If 1 carbon and 4 hydrogens combine to make methane, how many covalent bonds will be formed?
4 covalent bonds will be formed.
What are neutrons?
Particles with no charge (neutral) that are found inside an atom's nucleus.
How many covalent bonds can a carbon atom form?
A carbon atom can form four covalent bonds.
A REALLY difficult trivia question worth twice as many points! What is the electron orbital configuration for a carbon atom?
Two of them will be found in the 1s orbital close to the nucleus. The next two will go into the 2s orbital. The remaining ones are in two separate 2p orbitals.
On the Periodic Table, Carbon has an atomic number of 6. What does this mean?
6 protons, 6 neutrons, 6 electrons
An atom that has a positive or a negative charge, because it has either gained or lost an electron, is known as a(n) _.
Ion
What is Carbon's atomic number? Explain why it is assigned this atomic number.
The atomic number of carbon is 6. This is because it has six protons.
A pure substance that consists entirely of one type of atom is known as ____..
an element
What do chemists mean when they describe carbon as a "promiscuous" atom?
Carbon will bond with almost any kind of atom. This makes it possible to construct an almost endless amount of shapes.
What forms when atoms share electrons?
Covalent Bonds
Which carbon rich compounds are considered to be blueprints that are needed to make proteins?
Nucleic Acids such as DNA and RNA
Which Group on the periodic table will Carbon be found in?
Group 4A (USA Version) Group 14A (Europe)
What are covalent bonds?
Chemical bonds that are formed when atoms SHARE electrons.
A ____ is a substance formed by the chemical combination of two or more elements in a definite proportion.
A Compound
Is water an organic compound? Explain!
No. Water does NOT have carbon in it. To be considered an organic compound carbon must be part of its molecular structure.
