-
8 keys in a piano is an octave
-
Similar properties are repeated every 8th element
-
8 elements are a group
Frage 4
Frage
Why was Mendeleev's periodic table better than Newlands?
Antworten
-
He left gaps for undiscovered elements
-
He discovered the missing elements
-
He discovered the structure of an atom

Antworten
- True
- False
Frage 6
Frage
Why do elements in the same group have similar chemical properties?
Antworten
-
They follow Newlands law of octaves
-
Their atoms have the same number of electrons in their outer shell
Frage 7
Frage
When metals react they lose electrons so...
Antworten
-
The reactivity of metals in a group increases going down the group
-
The reactivity of metals in a group decreases going down the group
Frage 8

Antworten
-
Oxygen
-
A metal hydroxide
Frage 13
Frage
Group 1 metals form ionic compounds in reactions
Antworten
- True
- False
Frage 14
Frage
Why does reactivity increase going down group 1?
Antworten
-
The outer electron is less strongly attracted to the nucleus as the number of shells increase and the atoms get larger
-
The outer electron is more strongly attracted to the nucleus as the number of shells increase and the atoms get larger
Frage 15
Frage

Frage
Do transition elements react slowly or quickly with oxygen and water?
Antworten
-
Quickly
-
Slowly
Frage 17
Frage
Are transition elements useful as building materials?
Antworten
-
No because they are weak
-
Yes because they are strong and dense

- False
Frage 25
Frage
How do halogens bond with metals and non-metals?
Antworten
-
Metals: Form an ionic compound Non-metals: Bond covalently to form molecules
-
Metals: They don't bond with Non-metals: Form an ionic compound
Frage 26
Frage
Why does the reactivity of the halogens decrease going down group 7?
Antworten
-
The attraction of the outer electrons to the nucleus increases as the number of occupied shells increase
-
The attraction of the outer electrons to the nucleus decreases as the number of occupied shells increase
