Mid Unit Review: Study Pack 10 Science

What Are The “Horizontal Rows” On The Periodic Table?

Periods

What Are The “Vertical Rows” On The Periodic Table?

Groups

Why Are Noble Gases Special From The Other Groups?

They are unreactive because they already have a full valence shell - they’re already stable

What type of charge does a proton have?

Positive

What Type Of Charge Does A Electron Have?

Negative

What Approximate Mass Does A Proton And Neutron Have?  

1AMU, and is located in the nucleus 

How Do You Find Neutrons?

Atomic Mass - Atomic Number

What Does The Group Number Tell Us?

Tells us the number of valence electrons, if the number is 2 digit look at the ones place

What Does The Period Number Tell Us?

Tells us the number of electron shells

What Mass Do Electrons Have

Approx 0AMU orbiting the nucleus in shells

What Does AMU Stand For?

Atomic Mass Unit

What Does The Atomic Number Tell Us?

Tells us the exact number of electron’s and proton’s

What’s the Mass Number?

Rounded atomic mass

How many electrons can the 1st shell hold?

2 electrons

How Many Electrons can the 2nd 3rd 4rth shell hold?

8

What is the outermost shell called?

Valence Shell

What does the element symbol represent in the Lewis Dot Diagram?

Represents the nucleus + all inner shells 

What Do The Dots Represent In The Lewis Dot Diagram

Represents the valence electrons

Definition Of Isotopes

Element will have same number of protons but different numbers of neutrons which leads to different masses.

What Are Ions?

They are atoms or molecules that have gained or lost one or more electrons, resulting in a net electric charge. They can be positively charged (cations) or negatively charged (anions).

What Do Metals Lose (Ions)?

They lose electrons to form positively charged cations

What do Non-Metals Gain? (ions)

They gain Electrons to become negatively charged anions.

How to name Simple Binary? (One Non-Metal) (One Metal) (Naming Ions)

reverse cross the charges. (Not needed) (Check if charge has been reduced after crossing over, if so, multiply both charges) (not needed for this type of naming) Write full ions names

Whats A MultiValent Ion?

is an ion that can have more than one possible charge

How To Name Multivalent Metal And one non metal? (Stock method)

reverse cross charges, and use Roman numerals as the charge for the multivalent metal. Simplify when possible. (Check if charge has been reduced after crossing over, if so, multiply both charges) write full ions names

How To Name Multivalent Metal And one non metal? (Classic method)

reverse cross charges, and use (IC) (Higher charge) or (Ous) (Lower charge) as the charge for the multivalent metal. Simplify when possible. (Check if charge has been reduced after crossing over, if so, multiply both charges)

How To Name PolyAtomic Metal And one non metal?

reverse cross the charges, simplify when possible (Check if charge has been reduced after crossing over, if so, multiply both charges) (Do NOT CROSS OVER POLYATOMIC ION) write full ions names

How To Write Formula Simple Binary (One Metal And One Non Metal)

Write the ions, Cross over charges, simplify when needed

How To Write Formula Multi Valent Metal And One Non Metal? (Stock Method)

Write the ions, cross over charges, simplify when needed, if the multivalent ion ends in ic write higher charge if not write lower charge (ous). If it’s a Roman numeral, write it as that charge.

How To Write Formula Polyatomic Ion And One Non Metal?

Write Ions, Cross over charges (DO NOT CROSS OVER POLYATOMIC ION) (Put brackets if the polyatomic has a polyatomic ion (more than one), simplify when needed.
