Atomic Structure Quiz

Which of these is true about elements?. Atoms of each element contain a unique number of protons. Elements can only be broken down by an electrical current. All elements occur naturally in one form or another. Atoms of each element contain a unique number of neutrons.

Which of these is an element? Limestone Arsenic Pewter Air Cyanide Steel

Which of these can be called pure substances? Elements only Mixtures only Compounds only Compounds and mixtures. Elements and compounds. Elements and mixtures

Which of these is not an alloy? 9ct Gold Solder Cast IronSterling Silver Copper Piping Stainless Steel

In the Periodic Table a period is… A horizontal row A vertical column

On this periodic table the yellow elements are best described as: GasesNon-metalsMetals

Click on the element that is period 4, group 5

S This element is: Sodium Sulphur Strontium Sulphide

Hydrogen is H 1 1 From this you know…………….. It has one nucleus and one electron. It has one proton and one neutron. It has one proton and no neutrons

How many electrons does this element have? Cl

Elements in the same period of the periodic table…… All have the same number of electrons in their outer shell All have the same number of protons in their nucleus. All have the same number of electron shells

Being in Group 2 means that…. An element has 2 electrons An element has 2 electron shells An element has 2 electrons in its outer shell An element has 2 spaces for electrons in its outer shell

How many electron shells will this element have? Cl

The mass number of this element is: Cl

This element has an atomic number of ………

How many neutrons will this element contain? Cl

How many electrons will this element have in its outer shell? Cl

Which of these is true about ions.. ? Ions are always positively charged. Ions can from both ionic and covalent bonds Ions contain different numbers of protons and electrons. Some ions don’t have a charge in their natural state

How many groups are there in the periodic table?

Doh!
