The Structure of the atom
What is a proton?
A subatomic particle that has a + charge is located in the nucleus has mass and is equal to the atomic number.
Which one has a positive charge, and which one has a negative charge?
Cation
Anion
Cation= + charge (lose electrons)
Anion= - charge (gain electrons)
What are metals?
Solid at room temperature, expet for mercury, which is a liquid. Good conductors of electricity and heat. But some are better conductors than others. Metallic looking with a shiny luster. Malleable and can be hammered into sheets without breaking. Found on the left of the zigzag on the periodic table.
What are the periods on the periodic table?
The periods go left to right, there are 7 of them.
Non-metals + non-metals
What is a neutron?
Located in the nucleus, has mass and has no charge.
How many protons are in carbon?
6
What are non-metals?
Solid, liquid, and gass at room temperature. Poor conductors of electricity and heat. Not metallic, they have a dull luster and don't reflect light that much. They are brittle(break apart easily). Found on the right of the zigzag line on the periodic table.
What are families on the periodic table?
What do you combine to get an ionic bond?
metals(+) - non-metals(-)
They are outside of the necleus (Orbitals), virtually no mass, and has a - negative charge.
Do ions have the same number of protons and electrons?
No, ions have the same number of protons and different numbers of electrons
What are metalloids?
Have no characteristics. They share properties of both metals and non-metals. Found along the zigzag line on the periodic table.
What happens when you look across the periodic table?
The atomic number increases
Covalent bonds form when..?
What are neutral atoms?
They have the same number of protons and electrons, no overall charge, all atoms are neutral on the periodic table
Yes, they have different number of protons and neutrons
Is tin a metal, non-metal, or metalloid?
Metal
True or false
Mass numbers get bigger or smaller going down on the periodic table?
True
Ionic bonds form when..?
What is mass number?
In an isotope, are there the same number of protons and neutrons?
There are the same number of protons but different numbers of neutrons
Non-metal
How many families are in the periodic table?
18
Why do chemical bonds form?
To become stable (to have 8 rings)
