What are Ions?
Ions are electrically charged particles formed when atoms either gain or loose electrons.
1 of 33
What has the same electronic structure as ions?
The nobel gases have the same electronic structure as ions.
2 of 33
What do metal atoms form?
Metal atoms form positive ions.
3 of 33
What do non-metal atoms form?
Non-metal atoms form negative ions.
4 of 33
What is electrostatics force?
An electrostatic force is formed by difference in electrical charge (i.e positive and negative) between two particles.
5 of 33
What is an ionic bond?
The strong electrostatic forces of attraction between oppositely charges ions.
6 of 33
What is an electron?
An electron is a very small negatively charged particle.
7 of 33
Where is an electron in the atom?
The electron is found in the space surrounding the nucleus in the atom.
8 of 33
What does this loss of gain of an electron do?
This loss of gain of an electron leaves a complete highest energy level.So the electronic structure is the same of a nobel gas.
9 of 33
Do metals and non-metals go in the same direction when they ionise?
No,metals and non-metals go in different directions when they ionise.
10 of 33
What happens when metals ionise?
Metal atoms loose the electron or electrons in their highest energy level and become positively charged ions.
11 of 33
What happens when non-metals ionise?
Non-metals gain an electron or electrons from another atom to become negatively charges ions.
12 of 33
What is the rule for number of ions formed by a metal?
The number of charges of an ion formed by a metal is equal to the group number of the metal.
13 of 33
What is the rule for the number of ions formed by a non-metal?
The number of charges of an ion formed by a non-metal is equal to the group number minus eight.
14 of 33
What does hydrogen form?
hydrogen forms H+ ions.
15 of 33
Do carbon and silicon in group 4 form ionic bonds?
No carbon and silicon in group 4 usually form covalent bonds by sharing electrons.
16 of 33
Do the elements in group 0 react with other elements?
The elements in group 0 do not react with any other elements to form ions.
17 of 33
What is an ionic compound?
When metals react with non-metals,electrons are transferred from metal atoms to non-metal atoms forming ions.The resulting compound is an ionic compound.
18 of 33
What happen to the metals and non-metals in these reaction?
In these reactions the metal atoms give electrons to the non metal atoms.
19 of 33
What is an element?
A substance made of only one atom.
20 of 33
What are the elements in group one of the periodic table called?
The elements in group one of the periodic table are called the Alkali Metals.
21 of 33
What do the alkali metals form when they react with non-metals?
When alkali metals react with non-metals they form ionic compounds.
22 of 33
What type of charge do these compounds have?(Alkali metals)
These compounds have a single positive charge (i.e sodium forms sodium ions Na+.)
23 of 33
What are the elements in group seven of the periodic table called?
The elements in group seven of the periodic table are called The Halogens.
24 of 33
What happens when the halogens react with metals?
When the halogens react with metals they form ionic compounds.
25 of 33
What type of charge do these compounds have?(the halogens)
These compounds have a single negative charge (i.e chlorine forms chloride ions,Cl-)
26 of 33
What is a lattice?
A lattice is a regular grid like arrangement of the atoms in a material.
27 of 33
What happens to the ions in sodium chloride?
The ions in sodium chloride form a regular lattice in which ionic bonds act in all directions.
28 of 33
What is the formula for calcium hydroxide?
The formula for calcium hydroxide is Ca(OH)2
29 of 33
Why does sodium chloride have a lower melting point than magnesium chloride?
Sodium chloride has a lower melting point than magnesium chloride because sodium ions are larger and have smaller charge than magnesium ions so the ionic bonds are weaker.
30 of 33
How does sodium chloride conduct electricity?
Sodium chloride conducts when molten because it's ions are free to move.
31 of 33
What is the structure of Magnesium oxide?
The structure of magnesium oxide is a giant ionic lattice.
32 of 33
When does sodium chloride conduct electricity?
Sodium chloride conducts electricity when in a solution or molten.
