Why is it necessary to have a second letter in the symbol for elements?
If we only used one letter for each element, there could only be 26 elements.
Why where the lanthanide and actinide elements droped out of order on the periodic tabel?
The vertical columns of the periodic table are arranged to contain elements that have similar chemical and physical properties.The two rows at the bottom (called the Lanthanide and Actinide series) are elements that would all fit into group IIIB, in periods (horizontal rows) 6 and 7. since there is only one spot on the chart for all the elements in each series, they are listed separately at the bottom of the table.
What are the atomic numbers 81-100?
Elements 89-100 are the Actinide series of elements, most of which are radioactive, and some of which can only be made artificially. Elements 81-88 are also likely to be radioactive, but are naturally occurring.
Similarities between alkali metals and transitional metals?
Alkali metals and transitional metals are less alike than you may think. When you look at it, Alkali metals are all extremely reactive to water so must be kept under very controlled conditions. Transitional metals, however, really aren't very reactive to most household items. Actually, there are almost no common dangerous and/or reactive transitional metals. The few that come to mind are Mercury, Technetium (and this one doesn't even appear in nature), Tungsten, and possibly a few of the superheavies (104-112), and we honestly haven't spawned those elements for long enough to test them. Despite our best scientific efforts, these elements have only remained in existence for under very strict conditions. So where similarities go, the only one is that they are both metals.
Which elements in the periodic tables are transition elements?
Transition metals are the element in groups 3 through 12 of the periodic table. Scandium Titanium Vanadium Chromium Manganese Iron Cobalt Nickel Copper Zinc Yttrium Zirconium Niobium Molybdenum Technetium Ruthenium Rhodium Palladium Silver Cadmium Hafnium Tantalum Tungsten Rhenium Osmium Iridium Platinum Gold Mercury Rutherfordium Dubnium Seaborgium Bohrium Hassium Meitnerium Ununnilium Unununium Ununbium
What is the lining of the bladder?
The bladder is the only organ which features pseudostratified tissue.
Does Excel series name only have one data series?
Each series has one name. If you want more than one series, then each will have its own name. A series can have a lot of values in it, but can only have one name for that series.
What are the differences between galvanic series and emf series?
1)galvanic series is for both elements and alloys whereas emf series is only for elements 2)galvanic series tells about relative tendencies of corrosion whereas emf series tells about relative tendencies of displacement

Should A comma should appear after each item in a series?
Only if there are more than 2 objects in the series.
Are all elements made up of different elements combined?
No, each element is in basic form and are always only made up from themselves. When elements are combined this is a compound.
What is the relationship between the current leaving the source and the current through each load in a series circuit?
A: In a series circuit the current remains the same for each components only the voltage across each component will change and only if the components are of different value.
What are the atomic numbers 81-100?
Elements 89-100 are the Actinide series of elements, most of which are radioactive, and some of which can only be made artificially. Elements 81-88 are also likely to be radioactive, but are naturally occurring.
What part of speech is not only?
"Not only" is an adverbial phrase that is used to emphasize the significance of something by presenting it as the first in a series of a pair of elements. It is often followed by "but also" to introduce the second element in the series.

Why are there only 10 elements in the d row in the periodic table?
because d orbitals can hold maximum of 10 electrons. so only 10 elements possible for each shell
