Chemistry

Question 1

What is an Atom?

Answer 1

An atom is the smallest particle in any chemical element.

Question 2

What is Matter?

Answer 2

Anything that is made of atoms-Solids/Liquids/Gasses/Plasma.

Question 3

What are Atomic Particles?

Answer 3

One of the particles that an atom is made of- Electron/Neutron/Proton.

Question 4

What is an Electron?

Answer 4

An electron is the smallest part of an atom and is 0.000000… heavy in the AMU scale, It is found in the shells of an atom and emits an -negative charge.

Question 5

What is a Neutron?

Answer 5

A Neutron is used to help balance the protons in the nucleus and has a neutral charge; hence the name Neutron. It weighs 1 on the AMU scale.

Question 6

What is a Proton?

Answer 6

A proton is an atomic particle that also weighs 1 in the AMU scale like the Neutron, and is found in the Nucleus. The Proton has a +positive charge.

Question 7

What does AMU mean?

Answer 7

AMU is an acronym for Atomic Mass Unit, it is the scale of measurement used to express molecular and atomic weights.

Question 8

What is an Electron shell

Answer 8

An electron shell is the outside part of an atom, it is around the nucleus.

Question 9

What is an element?

Answer 9

Each of more than one hundred substances that cannot be chemically broken down into simpler substances. Each element is distinguished by its atomic number; the number of protons in the nuclei of its atoms.

Question 10

What is a compound?

Answer 10

Something that is made of two or more separate elements that are bonded

Question 11

What is the Periodic table of elements?

Answer 11

The periodic table of elements is a table that has all the chemical elements arranged in order of atomic number.
There is a total of 118 elements in the table.

Question 12

What is the Atomic number?

Answer 12

The atomic number is basically the number given to an element in the periodic table of elements that corresponds to the number of protons in the nucleus.

Question 13

What is Atomic Mass?

Answer 13

Atomic Mass is the weight of an element and it can be found by adding all the particles AMU weight.

Question 14

What is an Ion?

Answer 14

An Ion is an element that has a full valence shell. Also a charged atom

Question 15

What is a Cation?

Answer 15

A Cation is a positively charged ion that is created by removing electrons to get a full outer shell. All metals are Cations.

Question 16

What is an Anion?

Answer 16

An Anion is a Negatively charged ion that is created by gaining electrons to get a full outer shell. All non-metals are Anions. Anions usually had -ide on the end of a particle e.g. Chlorine atom = Chloride Ion

Question 17

Chemical symbol

Answer 17

The Chemical Symbol is an abbreviation of an elements Chemical name, It is usually the starting letters of it, if necessary to distinguish different elements. if it has a symbol that does not correspond to its current name, it means that it is originated from an older name.

Question 18

Chemical Name

Answer 18

The chemical name is the name given to each element in the periodic table.

Question 19

Periodic Law

Answer 19

A law stating that the elements, when listed in order of their atomic numbers, fall into recurring groups so that elements with similar properties occur at regular intervals.

Question 20

Metalloids

Answer 20

Metalloids are elements that have properties of both metals and non-metals.

Question 21

Lustre

Answer 21

The shine or radiance of something.

Question 22

Conductors

Answer 22

Something that can conduct or carry through.

Question 23

Malleable

Answer 23

Something that can easily be broken or shattered.

Question 24

Ductile

Answer 24

Something that can be drawn into a thin line.

Question 25

Brittle

Answer 25

Something that is fragile or can easily break.

Question 26

Monatomic

Answer 26

The formation name for single atoms.

Question 27

Molecular

Answer 27

The formation name for groups of chemically bonded atoms.

Question 28

Lattices

Answer 28

The formation name for large three-dimensional grids.
