15

What is the name of group 18 of the periodic table?

Noble Gases

10

What is a chemical compound?

A substance formed by 2 or more atoms chemically joined together

15

Why do atoms form compounds?

To become stable by gaining, loosing or sharing electrons

15

Are all atoms stable?

No, most atoms are UNSTABLE

15

Which atoms are stable? Why?

The Noble Gases (group 18) because they have a FULL valence shell.

20

Which group/family of elements is the most REACTIVE?

Group 17; they only need 1 electron to become stable

15

When a neutral atoms gains 1 electron, it becomes a POSITIVE/NEGATIVE ion?

negative

15

When a neutral atoms gains 1 electron, it becomes a NEGATIVE ion. WHY?

Because now it has more electrons that protons

15

What are the 3 types of chemical bonds?

Ionic bonds, covalent bonds and metallic bonds

15

Covalent bonds happen between METAL/NON-METAL and METAL/NON-METAL elements.

non-metal and non-metal elements

15

In covalent bonds, atoms GAIN/LOSE/SHARE electrons.

share

15

Can covalent bonds form between 2 atoms of the SAME element?

Yes, for example CL-CL

15

In covalent bonds, atoms share electrons from WHICH shell?

valence shell or the outer shell

15

In covalent bonds atoms share electrons. To do this, atoms ________ (verb) their valence shells.

overlap
