Atomic Structure
Flashcards do conjunto (13)
- 1What do atoms consist of?Atoms consist of sub-atomic particles. These are electrons surrounding a nucleus filled with protons and neutrons.
- 2What is a relative mass?The number of times heavier a particle is compared to another.
- 3What is an electron?An electron is a sub-atomic particle which is negatively charged and has a negligible mass.
- 4What is a neutron?An neutron is a sub-atomic particle which has no charge and a relative mass of 1.
- 5What is a proton?A proton is a sub-atomic particle which is positively charged and has a relative mass if 1.
- 6What surrounds the nucleus?The shell AKA orbital AKA energy levels.
- 7How can you identify an atom/element?An atom/element can be identified by the number of protons it contains.
- 8What are the numbers associated with each element in the periodic table.The number below the symbol of an element is called the proton or atomic number.
The number above the symbol of an element is called the atomic mass. It is also the number of protons plus the number of neutrons in an atom - 9How are protons and electrons in an atom linked?The number of protons and electrons are equal in an atom.
- 10Why are atoms neutral?Atoms are neutral because there are the same amount of electrons and protons in an atom and neutrons have no electrical charge.
- 11How many electrons can the first shell in an atom contain?It can contain up to and including 2.
- 12How many electrons can the second shell in an atom contain?It can contain up to and including 8.
- 13How many electrons can the third shell in an atom contain?It can contain up to and including 8.
