All you have to do is look on your Periodic Table of elements. Metals are to the left and non-metals are to the right. This way we know group four are metals.

What describes a property of all of the Group 4 A elements?
they are metals.
What is the oxidation number of group 14 elements?
-4 for nonmetals and +4 for metals
Are there more metals than non metals?
Yes, 3 or 4 times as many elements are metallic. Note, the whole left AND bottom portions of the Periodic Table are metals.
How do you use the periodic table to find the charge of an anion?
It is really simple. For the groups 1A and 2A, the charges will be +1 and +2 respectively. For example, Na (sodium) is in group 1, therefore it has a charge of (Na)+ . Ca (calcium) is in group 2, therefore it has a charge of (Ca)+2 .The groups that have a B after the number are called transition metals because they form cations with various charges. For the metals in group 3A (Aluminum, Gallium and Indium will have 3+ charge). However, Thallium, which is in the same group can have different charges of (+1 and +3).Now for the NON metals from groups 4A to 7A is easy to predict the charge because the elements in group 8A are called noble gases, which do NOT have charge, they are inert. The elements in group 7A will have -1 charge, the elements in group 6A will have -2 charge, the elements in group 5 will have -3 charge, the elements 4A will have -4 charge.REMEMBER THAT THIS ONLY APPLIES FOR NON METALS.
Which non metal can make 4 covalent bonds to other elements?
All non-metals in group IV will be able to form 4 covalent bonds with other elements. They need 4 more electrons to form the octet structure in their valence shell. Hence, they can form 4 single covalent bonds to constitute the covalent structure. On the other hand, elements in group III, such as boron, can also make 1 double bond and 3 single bonds to share 5 electrons to achieve octet structure.
What are the 4 main categories of elements found on the periodic table?
- The Group 1A elements are called alkali metals. - The Group 2A elements are called alkaline earth metals. - The nonmetals of Group 7A are called halogens. - The Group 8A elements are called the Noble Gases
Which family of elements only contains one nonmetal element?
Group 4 (Now 14) of the Periodic Table contains only one non-metal; Carbon (C). All the rest of the elements in this group are metals. The metals in Group 4(14) are;SiliconGermaniumTinLead
What describes a property of all of the Group 4 A elements?

What is the oxidation number of group 14 elements?
-4 for nonmetals and +4 for metals
Where are transition metals tocated?
Transition elements are in group 3 to 12 in period 4 to 7
What family is a very reactive group of mostly nonmetals whose gain or share one electron in chemical reactions?
Group 17 elements, 'Halogens', have seven electrons in their valence shell and show the valency of 1. 4 of the 5 elements in that group are non metals including fluorine, which is the strongest.
Where are the metalliods found on the periodic table?
Metalloids are found approximately in the middle between the metals on the left and non-metals on the right.
Are there more metals than non metals?
Yes, 3 or 4 times as many elements are metallic. Note, the whole left AND bottom portions of the Periodic Table are metals.

What two atoms share 4 electrons?
Carbon and silicon are two elements that share four electrons while bonding. Occasionally, in compounds like sulfur tetraoxide, elements other than in group 14 also share exactly four electrons.
What group of elements are contained in the p-block?
The p-block metals are aluminum, gallium, indium, thallium, lead, tin, bismuth, and polonium. also, ununtrium, ununquadium, and ununpetium are sometimes comsidered p-block metals, although they are man-made.
