States Of Matter
what are the main states of matter (3)
Solid, Liquid, Gas
what is the atomic theory?
The scientific idea that all matter is made of tiny particles called atoms.
What is the difference between a physical and a Chemical Change?
Physical Changes happen when something Changes Form but stays the same substance. Chemical Changes happen Usually when something gets changed and is difficult to reverse and a new substance formed is with new properties
What is The Measurement Of A pH scale?
0-14
What is a Periodic Trend?
A Pattern in Element properties that repeats across the periodic table
When Water Freezes, What State Does it Become?
Solid = Ice
what is the Greek word for Atoms?
atomos
When eating a dish or something, What change is happening while the food is traveling through your body?
Chemical Change
In pH Terms, From Which number on the scale is considered a Neutral
7 - 7.99
As You move left to right across the periodic table what generally happens to the element, specifically their Atomic Size?
Atomic Size Decreases
When A Chocolate Bar Is Melted, What State of Matter Does It become?
Liquid
Who were The First Humans to ever make a Compromise About Atoms?
Ancient Greeks
When Vinegar and baking soda mix, What Change is occured?
Chemical Change
What Range is Blood in The pH scale?
7.45 (Neutral)
As you move down a group, what happens to the atomic radius, and why?
It Increases Because More Energy Levels ( Electron Shells) are Added
What is The Fourth State Of Matter?
Plasma
who Developed the first Atomic Model
John Dalton
Crystalization is a form of Forming crystals from a solution (like salt from saltwater) changes the substance from dispersed ions to a structured solid, what kind of Change is This?
Physical Change
what makes water a neutral substance?
an equal amount of positive hydrogen ions and negative hydroxide ions, balancing acidity and basicity
Why Do Elements Become More Reactive As You Go Down Group 1 (alkali metals)?
The outer electron is farther from the nucleus and easier to lose
What State Of Mattter Is Lighting In?
Mostly Plama. But is also mixed with Different types of Solid Molecules, Liquid, and Gas too
What truly is a atom or atoms?
Atoms are actually empty space composed of a dense nucleus, with buzzing electrons and a mass concentrated in the nucleus but volume in the electron cloud
when tempering steel, what change is being compromised?
Physical Change
Currently, What is the most acidic Compound in the World?
Fluoroantimonic Acid, A range of -31.3 (Acidic)
Element A is Larger in Atomic size and Element B is higher in Electronegativity. Which Element Is Farther to the Right on The periodic Table?
Element B is farther to the right. Because the atomic size decreases while Electronegativity increases, so the the smaller atom actually pulls electrons more strongly.
