Bohr's Diagrams Flashcards
What is the electron configuration of the first 20 elements?
2.8.8.2
What are the three subatomic particles of an atom?
Proton, Neutron, Electron
What charge does a proton have?
+1
What charge does a Neutron have?
Neutral or 0
What charge does a electron have?
-1
What determines the Atomic Number and therefore the type of element an atom is?
The number of protons.
What is an isotope?
An atom with a different number of neutrons to protons.
What is a group on the periodic table?
A vertical column. Elements in the same group have the same number of valence electrons.
What are the three steps to drawing a Bohr diagram?
- Determine the number of protons, neutrons, and electrons.
- Place the protons and neutrons in the nucleus.
- Arrange the electrons into their shells.
Why is the electron configuration of an atom important?
It tells us how likely an atom is to react with another. Determines how atoms will bond (ionic or covalent). Tells us how stable an atom is. Explains why some elements lose electrons and why some gain.
What is an ion?
An ion is any atom with a positive or chemical charge. It occurs when an atom gains or loses an element.
What is a cation?
A positively charged ions.
What is an anion?
A negatively charged ions.
Metals tend to form what type of Ion?
Cations. They tend to lose electrons because they have low amounts in their valence shells.
