Lead was commonly used in the past as a component in solder used by plumbers for joining pipes together. However, due to its toxicity, lead-based solder is no longer used for Plumbing applications, and safer alternatives are now available.
Copper is the main element of high quality plumbing.
Inexpensive plumbing used in tract homes is generally iron.
Inexpensive plumbing used in businesses is generally PVC (polyvinylchloride, a type of plastic).
In the past, lead. It is no longer used because it is toxic to humans.
The Latin word "plumbum" means "lead" - hence the element's chemical symbol Pb.
There was a time when led was the preferred choice for the construction of water pipes. Nowadays, elements that are used for water pipes include iron, steel, and copper.

How do the isotopes of given element differ from one another?
isotopes of a given element differ in the number of neutrons they have.
What is the atomic number in a given element equivalent to?
The atomic number of an element is equivalent to the number of protons in the nucleus of an atom of that element. It determines the element's identity and its place on the periodic table.
What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
what are the 4 points in Dalton's atomic theory?
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
How can you say given element is more oxidative?
no
What element is given by gallium?
The element of gallium is Ga3.
How do the isotopes of given element differ from one another?
isotopes of a given element differ in the number of neutrons they have.
Why did scandium get its symbol?
Every element is given a symbol and so, scandium being an element, was also given one.
Who were the plumbers in the Watergate scandal?
The administration of Richard Nixon was obsessive to the point of paranoia regarding "leaks" of information the the press & other media. The men given the job of plugging those leaks were given the nickname of "plumbers". (Plumbers are also reputed to 'get rid of the sh*t)

What device analyzes the light given off when an element is burned?
A spectrometer analyzes the light given off when an element is burned.

What is the name given to the side element in a casement window?
The side element is called a vent.
What information is given by the group number of an element?
Indications about the general chemical properties of this element.
The nuclei of all atoms of a given element always have the same number of what?
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
