What is the element whose symbol is Ma on the nutritional facts?

The element with the symbol "Ma" does not exist on the periodic table. It is possible that the symbol is a typo or error. Common elements found on nutritional facts labels include sodium (Na), potassium (K), magnesium (Mg), and manganese (Mn).


What change occurs in valence shells of elements as you move from left to right in any given row of the periodic table?

From left to right on the periodic table, the elements in each group (column) have one more electron in their outer shell. For example, sodium (located on the far left side of the periodic table) has only one valence electron. Helium (located on the far right side of the periodic table) has 8 valence electrons. If the periodic table you're labels the 'A' and 'B' groups, then seeing the pattern is fairly easy. When you ignore the 'B' groups (transition metals), a very easy rule applies: whatever group (column) an element is in, that's the number of electrons in the outer shell. Elements in Group IA (like sodium) have one valence electron. Elements in Group IIA (like calcium) have 2 valence electrons. Likewise, elements in Group IIIA (like aluminum) have three valence electrons. This rule applies to all elements located in 'A' groups. For example, simply by looking at the periodic table, you can tell that fluorine has seven valence electrons because it is located in Group VIIA. In answer to your question, from left to right, on the periodic table, the number of valence electrons an element has increases.


What is Group A called in periodic table?

In the older periodic table, each group was divided into A & B sub-groups. The only problem with that was that there were two different conventions about which elements were labelled "A" and which were labelled "B". Groups 1 & 2 were clearly 'A' (elements like sodium and calcium) and 11 & 12 were clearly 'B' (elements like copper and zinc). But groups 3 through 10 were labelled 'A' in one convention and 'B' in another, and the opposite labels were used for groups 13 through 18.With the second labelling convention, groups labelled 'A' were known as 'main group elements', and groups labelled 'B' were 'transition metals', and that is still the case.Thus in the newer IUPAC scheme, groups 1, 2, and 13 through 18 are called 'main group elements'.


What are the recycling restrictions on plastic labels?

Generally there are no recycling restrictions on plastic labels. These labels are removed during the final cleaning stage of the recycling process by the secondary manufacturer.


How to comply with OSHA right to know program at workplaces with chemical handling requirements?

Inform workers what they're exposed to by posting durable and legible chemical labels. Chemicallabels.com offers a wide range of durable chemical safety labels that both inform and caution material handlers of the hazards they're encountered with. Popular labels include NFPA stickers, OSHA chemical labels, and MSDS labels.

What are in groups 3 through 12 on the periodic table?

Elements in groups 3 through 12 on the periodic table are known as the transition metals. These elements have properties that include high melting points, ductility, and the ability to form colored compounds. They are widely used in industrial applications, jewelry, and electronics due to their unique properties.


If you know the name of a material or item how could you find out if it is an element?

Check to see if it is on the periodic table. http://ptable.com/ To do this you must not only know its properties but what else is in the item To do this look at the tags, labels etc. and then use a element table you can ask your science teacher for one or seach the net. but elements are one 'pure' form of the metal

Why would you want to view a label's boundaries before printing?

You want to be certain that they print properly. Printing labels can be awkward, and if it is not done properly a lot of labels can be ruined. So you need to know the sizes, know where the boundaries are and be sure to have the labels correctly in the printer. You should also do a test print, to see if they are correct before trying to print a lot of labels.

Where can one find more information about family labels?

Labels suitable for use by the whole family can be purchased at a number of stores. Amazon and eBay offer the best prices but if one prefers to shop instore, try Staples or Ryman.
