Flashcards in Atoms and Bonding Deck (50)
the smallest particle of matter
Every atom is made up of ____ different types of particles
In the nucleus there are ____ and _____
Protons are positively charged, negatively charged, or uncharged ?
Neutrons are positively charged, negatively charged, or uncharged ?
Flying around the nucleus are _____
Electrons are positively charged, negatively charged, or uncharged ?
The atomic number of an element is _____
the amount of protons
The atomic mass of an atom is the number of...
protons + neutrons
Do electrons have a mass?
No, they are so small that they effectively have no mass so we do not include them in the atomic mass
What are ions?
Ions are atoms that have lost or gained electrons
If you gain or lose _____ it affects the overall electrical charge of an atom.
Are ions naturally electrically charged?
An isotope of an element is ....
a variation of that element that has a different number of neutrons
Does an isotope change an atoms atomic mass?
Yes, because the number of neutrons is different, and neutrons carry mass
an example of an isotope is?
Carbon-12 to Carbon-13
Carbon-12 is the most common type of carbon, which has 6 protons and 6 neutrons. If a carbon atom forms that has an extra neutron then that is called Carbon-13.
Carbon-12 has ____ protons and ____ neutrons
6 and 6
Is Carbon- 12 the most common type of carbon?
Why is carbon-13 an isotope of Carbon-12?
Because the Carbon atom carries one more neutron, and thus has a larger mass.
What can Isotopes be used for?
to determine how old things are
Is Carbon-14 used to date archeological materials?
When two or more atoms become linked together, that is called...
Chemical bonding is when ____ or more atoms ____ together.
After two or more atoms are chemically bonded, the resulting arrangement of atoms is called a...
what is a molecule?
a group of atoms bonded together
What are two different ways/processes of chemical bonding?
ionic bonding and covalent bonding
An ionic bond happens when
an atom that has a very strong positive charge in its nucleus attracts electrons from other atoms. The atom that steals an electron will become negatively charged, and the atom that loses an electron will become positively charged. Consequently, they will be stuck together because of their opposite charges like a magnet.
if you have an atom that steals an electron from another atom, the thief atom will become _______ charged and the victim atom will become ______ charged.
In a covalent bond the two atoms _____ electrons.
