There are ten elements in each transition series of the Periodic Table because each series corresponds to the filling of the d-orbitals, which can hold a maximum of ten electrons. The transition metals are defined by the presence of electrons in these d-orbitals, and the elements in each series represent the sequential addition of electrons to these orbitals. Consequently, each transition series encompasses ten elements, from scandium (Sc) to zinc (Zn) in the first series, for example.

Why is it necessary to have a second letter in the symbol for elements?
Having a second letter in the symbol for elements is necessary to distinguish elements with similar symbols. It helps identify the specific element and avoid confusion when referencing or working with different elements.
Is a charaterists of actinides?
Actinide series, a series of radioactive metallic elements in Group 3 of the periodic table. Members of the series are often called actinides, although actinium (Ac, atom no. 89) is not always considered a member of the series. The series always includes the 14 elements with atomic numbers 90 through 103. The other members are (in order of increasing atomic number) thorium, protactinium, uranium, neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, and lawrencium. Thorium (90) isotope-232 and uranium-238 are the only actinides found in the earth's crust in appreciable quantities, although small amounts of neptunium and plutonium have been found in uranium ores. Actinium and protactinium (91) are found in nature as decay products of some thorium and uranium isotopes. All the others have only been synthesized in small quantities (see synthetic elements). Study of the properties of the actinides is hampered by their radioactive instability. It is known, however, that all members of the series resemble actinium and each other in their chemical properties and that they have a strong chemical resemblance to their homologs in the lanthanide series. The actinides are reactive and assume a number of different valences in their compounds. As the atomic number increases in this series, added electrons enter the 5f electron orbital. Elements in this series with atomic numbers greater than that of uranium (92) are called transuranium elements. Elements with atomic numbers greater than 103 are not members of the actinide series; element 104 (rutherfordium) is the first of the transactinide elements.
What series are called elements 57 to 70?
Elements from atomic number 57 (Lanthanum) to 71 (Lutetium) are called the Lanthanides. Lanthanide means "like Lanthanum" and so, the Lanthanides are based on Lanthanum. Only one of the Lanthanides is radioactive: Promethium (Pm - No. 61)
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.
Are gases the only elements?
No, gases are not the only elements. Elements can exist in different states of matter, including solid, liquid, and gas. There are 118 known elements on the periodic table, each with its own unique properties.
Should A comma should appear after each item in a series?
Only if there are more than 2 objects in the series.
An element in the activity series can replace any element in?
Below it on the list on the periodic table
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.
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 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
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
Why is it necessary to have a second letter in the symbol for elements?
Having a second letter in the symbol for elements is necessary to distinguish elements with similar symbols. It helps identify the specific element and avoid confusion when referencing or working with different elements.
What is a rule for current flowing round a circuit?
In a series circuit, the current at every point in the circuit is the same. This is a consequence of Kirchoff's Current Law, which states that the signed sum of the currents entering a node must equal zero. Since a series circuit consists of nodes with only two elements connected to each node, it follows that the current at every point in a series circuit is the same.
