Test practice one

Hydrogen-1: This way of representing elements is called the elements???

Isotope name

What is this ?

Isotope symbol

The number of protons + neutrons =

Mass number

Positively charged subatomic particle: this subatomic particle also determines the atoms identity what is it ?

Proton

At the center of the atom it contains almost all of the mass of an atom but takes up almost none of the volume

Nucleus

This ___ is equal to the number of protons in an atom what is it called

Atomic number

The location of electrons name

Electron cloud

Negatively charged subatomic particle, also this subatomic particle does not contribute to the mass number of the atom what is it???

Electron

What is the neutral subatomic particle?

Neutron

These are atoms that have a charge due to extra electrons or fewer electrons what is it??

Ion

These are atoms of the same element but due to extra electrons or fewer electrons it is a???

isotope

What is the positively charged subatomic particle ?

Proton and remember it by positive= Proton both start with p

What is the negatively charged subatomic particle also determines??

It is electron and remember it by electron=electricity=danger=negative

What is the location with the moss mass in the atom what is it?

Nucleus and remember it by Nuc=mass

This is the location with the least mass in the atom what is it?

Electron cloud and remember it by least mass number=cloud

Guess where it goes

Symbol = 133 Cs 55 Atomic number = 55 Mass#133 protons =55 Electrons =55 Neutrons = 78

Guess where the things go

Name = Iodine -128 Symbol = 128 I 53 Atomic #= 53 Mass =138 Protons=53 Electrons =53 Neutrons =78

Guess where it goes

symbol = 14C 6 Atomic#= 6 Mass= 14 Protons =6 Electrons =6 Neutrons=8
