What type of atoms are involved in covalent bonds?
Non-metals
1 of 37
What happens to the electrons?
They shared some of their outer electron,
2 of 37
What structure is formed in a covalent bond?
A noble gas structure with a full outer shell,
3 of 37
How are atoms with covalent bonds held together?
By electrostatic attraction between the nuclei and shared electrons,
4 of 37
Explain electrostatic attraction in a hydrogen atom?
The hydrogen atom consists of two protons held together by a pair of electrons. The repulsive and electrostatic forces balance when the nuclei are a particular distance apart,

What happens in a double covalent bond?
Four electrons are shared in a covalent bond

What happens in a double covalent bond?
Four electrons are shared in a covalent bond
7 of 37
What happens in a double covalent bond?
Four electrons are shared in a covalent bond
8 of 37
Do covalent bonds have high or low melting temperatures in molecules?
Low melting temperatures
9 of 37
What happens in a double covalent bond?
Four electrons are shared in a covalent bond
10 of 37
Do covalent bonds have high or low melting temperatures in molecules and why?
Low melting temperatures as the strong covalent bonds are only beteen the atoms within this molecule and only weak attrac

What happens in a double covalent bond?
Four electrons are shared in a covalent bond
12 of 37
Do covalent bonds have high or low melting temperatures in molecules and why?
Low melting temperatures as the strong covalent bonds are only beteen the atoms within this molecule and only weak attraction between molecules so dont need much enegy to move apart,

Do covalent bonds have high or low melting temperatures in molecules and why?
Low melting temperatures as the strong covalent bonds are only beteen the atoms within this molecule and only weak attraction between molecules so dont need much enegy to move apart,
15 of 37
Can covalent bonds conduct electricity?
No, they are poor conductors and are insulators as molecues are neutral overall

18 of 37
Can covalent bonds conduct electricity?
No, they are poor conductors and are insulators as molecues are neutral overall so no charged ions to carry the current,

What is a dative or co-ordinate bond?
An atom donates both the electrons in a covalent bond with another atom

What is a dative or co-ordinate bond?
An atom donates both the electrons in a covalent bond with another atom which is 'electron-deficient.'
