Ions And Bonding

Question 1

What are an ions?

Answer 1

Atoms or a group of atoms that have an electrical charge, due to losing or gaining a proton or electron

Question 2

What are cations?

Answer 2

Atoms that are positively charged +1

Question 3

What are polyatomic ions?

Answer 3

A group of atoms that join together to form a charge-meaning they have either more protons then electrons, or more electrons then protons giving it a charge

Are ions made up of more than one type of atom

Behave ( react ) in the same way as simple ions

Question 4

What is an anion?

Answer 4

An atom that has a negative charge

Question 5

When are atoms most stable?

Answer 5

When they have a full outer shell of valence electrons like group 8a

Question 6

What is it called when atoms have a full outer shell of valence electrons?

Answer 6

The octete rule

Question 7

How do atoms become cations?

Answer 7

When they lose electrons they become positively charged

Question 8

How to atoms become anions?

Answer 8

When they gain electrons they become negatively charged

Question 9

What is an ionic bond?

Answer 9

Where a metal ( positive) and a non metal ( negative) connect together

Electrons get stolen and opposites attract

( lattice structure ( box like shaped )

Question 10

How is an ionic bond formed?

Answer 10

When a metal gives an electron ( making it a positive charge ) to a non metal ( giving it a negative charge ) because of this both atoms become charged. Ions have opposite charges so they stick together

Question 11

Is hydrogen a metal or non metal?

Answer 11

Non metal despite being on the periodic table under metal! Only exception to the rule

Question 12

What is a molecular or covalent bond?

Answer 12

Is the chemical bond between two non metals and they share electrons

( made up of molecules ) ( which is a bunch of atoms stuck together in a clump )

Question 13

What sticks covalent compounds together

Answer 13

Because there sharing electrons together

Question 14

What sticks ionic compounds together?

Answer 14

Because one has stolen the others electrons and created opposite charges which in return they become stuck together because opposites attracts

Question 15

What is a hydrogen bond?

Answer 15

A type of intermolecular bond ( form between molecules ) they can exist between atoms in different molecules or in parts of the same molecule. Usually fluorine,nitrogen or oxygen

Question 16

What does polar mean?

Answer 16

Polar molecules occur when there is a electronegativity between the bonded atoms

Question 17

What does non polar mean?

Answer 17

Non polar molecules occur when electrons are shared equally resulting in a non charge

Question 18

What is a polar bond?

Answer 18

Is a covalent bond between two atoms where the electrons forming the bond are unequally distributed.

Question 19

What is a simple ion?

Answer 19

Are formed when a single atom gains or loses electrons
