practice
100

describe pattern/shared charateristics that elements in the same group share vs elements in the same period

group- share electrons

periods- atomic orbitals

100
which number tells you identity of element and most common form of element

atomic #, atomic weight

200

explain why elements in the same group often have similar properties 

they have a similar amount of electrons
200

what way do periods go and what do they tell you

periods are horizontal and tell you how many shells it would have

300

differentiate between metals, nonmetals, and metallouds

metals are good conductors, not mentals are poor, and metalloids are semi conductors

300

what way are groups and what do they tell you 

groups are vertical and they tell you amount of valence electrons

400

 explain electronically neutral and give a name for atom thats not neautral

it has charge of 0, and ions
