Unit 1 Test Review Flashcards
How do you find the protons, electrons, and neutrons
The protons and electrons come from the atomic # and you subtract that # from the atomic weight
How do you know how many e’s elements want using the periodic table
The Roman numerals
What is an isotope
A element with more or less neutrons
Why does the masses of various elements have decimal values
This is because isotopes have different weights and in order to find the average of the elements weight you need to add them all together E divide by the percentage of how many you have
What is the difference between isotopes and radioisotopes
Isotopes are elements with more or less neutrons. Radioisotopes are unstable isotopes that emit radiation from the nucleus breaking down
What is radiation
Radiation is the chunks of the nucleus that hits you when the element is trying to break down to a more stable form
What is alpha radiation?
4 he 2
What is beta radiation?
O e -I same form as a electron
What is gamma radiation?
0y0 /y
What does a proton look like?
1p1/ 1h1
What is neutron
1n0
Positron
0e +1
What is the difference between ionic & covalent compounds?
Ionic compounds are formed with a non-metal and a metal, a covalent compound is made with 2 non metals
What is electronegativity? Where can you find it?
Electronegativity is a property that determines how strongly electrons in a chemical compound are held together , you can find it on the periodic table
