Intro to Chemistry Unit 1 Test

What separates the elements on the Periodic Table between metals and non-metals?

This type of bond happens between metals and non-metals

A substance that cannot be broken down any further and is made up of one type of atom

A substance that is chemically bonded and cannot be separated without chemical change

The maximum capacity of electrons in the third electron shell is

This number in the formula is what shows how many atoms of an element are in a compound

This type of bond is between non-metals and other non-metals

What makes an atom a type of atom?

A molecule made up of only 2 atoms. Example: NaCl

Protons, neutrons and electrons are all what type of particle?

What is a charged atom called?

The vertical columns on the Periodic Table are called what?

This type of mixture is not evenly mixed and can easily be distinguished.

Tells how many protons are in the atoms of that element

Where are the protons of an atom located?

This type of bond is the sharing of valence electrons

This type of mixture is evenly mixed and not easily distinguishable. Example: salt water

Protons have what charge?

What area of science is the study of matter and the interactions between matter?

This man theorized that electrons were orbiting the nucleus in shells outside the nucleus

What overall charge does an atom have

An atom with a different amount of neutrons than protons

The center of the atom is called what?

The letters on the Periodic table

The smallest unit of a chemical compound, that can take place in a chemical reaction.

Sugar is an example of what type of bond?

Is not a whole number because it's average sum includes isotopes

Electrons have what charge?

These elements have properties of both metals and non-metals

The atomic number for Carbon is 6. If an atom of Carbon has 10 electrons what is it?

All elements in a family have this in common

What makes an element that particular element?

The 3 classifications of matter are elements, compounds and mixtures.

The electrons on the outside shell of an atom are called

Makes up all of matter

Most of these elements are on the right side of the zigzag line

A substance that is not chemically bonded together, only physically put together
