In a chemical formula what is the number of atom for each element usually indicated by?
its usually indicated by a subscript! :D
What part of the electron configuration of an element corresponds to the periodic of element?
Well, giving the example of Bromine (1s22s22p63s23p64s23d104p5) the s orbitals (represented by the letter s) are the first two groups/families (1-2) with the exception of helium, the p orbitals (represented by the letter p) are the last six groups/families (13-18), and the d orbitals (represented by the letter d) are the transition metals (3-12). Not included in bromine are the f orbitals (elements 57-70 and 89-102)
Is a cation isoelectric with the element before or after it?
No necessarily. Although the alkali metal cations are, most other cation-forming elements (metals) are not as many of them lose more than one electron. It is even more complicate for the transition metals as they can move electrons between their s and d orbitals.
What is the atomic mass number of element d?
The atomic mass number of an element is the total number of protons and neutrons in its nucleus. It is denoted by the symbol A. If you provide the symbol or name of element d, I can tell you its atomic mass number.
What is the d block element with the smallest atomic number?
Scandium. Its atomic number is 21. It is the first d block element.
The number of protons in an atom of an element is the elements?
the number of protons in one element determines the atom's
A substance that contains only one kind of atom is called- a A nuetron b A molecule c An element d A compound Which one Thanks?
An element is the correct answer
Is sulphur an element or a compound or a homogeneous mixture or a heterogeneous mixture?
sulphur is an element, as it is a pure substance made of one type of atom..! :D
What does the element DO stand for?
There is no ELEMENT with the symbol "DO" however, it would be the molecule which is one atom of deuterium (D) and one atom of oxygen (O). Deuterium is an isotope of hydrogen. This molecule would be called deuterium oxide.
Why d block element are called transition element?
d block elements, transition metals, transition elements are synonyms.The definition of d block after the IUPAC recommendation is "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete dsub-shell".
In a chemical formula what is the number of atom for each element usually indicated by?
its usually indicated by a subscript! :D
What is the name for element d?
'D' (capital 'd') is sometimes used for deuterium, one of the isotopes of hydrogen. Please see the link.
What is the atomic number of an atom with symbol of CD?
CD is an invalid element symbol. Element symbols must only have one capitalized letter. This is also an invalid substance as there is no element with the symbol "D" However "C" is a valid symbol for Carbon and the atomic number is 6
What are the US Congressional districts in Philadelphia?
US Districts In Philadelphia:First District represented by Bob Brady (D).Second District represented by Chaka Fattah (D).Eigth District represented by Patrick Murphy (D).Thirteenth District represented by Allyson Young Schwartz (D).
How is the number 500 represented in Roman numerals?
The number 500 is represented in Roman numerals as "D".

What elements make up the compound mercury?
Mercury is an element itself. It is the only metal that is a liquid in room temperature. This d-block element has a silver-like color.
