(CNN) It's not something that will be listed among the ingredients, but chocolate contains some lead. Manufacturers say it's trace amounts, and it makes its way into chocolate as a naturally occurring element that is absorbed by the cacao plant.

Lead pencils contain graphite (a form of carbon), not lead. In fact, contrary to what many people believe, lead pencils never were made with lead. The ancient Romans used a writing device called a stylus.

Some are obvious, like hydrogen (H), oxygen (O), carbon (C), uranium (U), helium (He), or calcium (Ca). Some seem to make no sense at all, like lead (Pb), silver (Ag), and gold (Au).

Because bronze is an alloy of tin and copper so it is not included in the periodic table. The elements in the periodic table is just pure element and just contain one kind of atom like iron, copper, … But steel is not an element it is a combination of iron and carbon just like bronze.

The elements boron, silicon, germanium, arsenic, antimony, and tellurium separate the metals from the nonmetals in the periodic table. ... The structures of these elements are similar in many ways to those of nonmetals, but the elements are electrical semiconductors.

Depending on the author, one or more from selenium, polonium, or astatine are sometimes added to the list. Boron sometimes is excluded, by itself, or with silicon. Sometimes tellurium is not regarded as a metalloid. The inclusion of antimony, polonium, and astatine as metalloids has been questioned.

The columns of the periodic table are called groups. All elements in a group share the same number of valence electrons. The three broad categories of elements are metals, nonmetals, and metalloids. Most elements are metals. Nonmetals are located on the righthand side of the periodic table.

Technically it is hard to claim completely "lead free". As any raw material in the world would have some degree of contamination. Unlike crystal, Pyrex should have less than 0.1 part per million (or 1 in 10 million) of lead. ... So there should be no worry about lead.

Most elements are either metals or nonmetals. Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium itself is classified as a metalloid.

The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element.

Lead has a very high density and Alpha, beta particles cannot penetrate through it (lead). This helps to concentrate the beam of this particles towards the gold foil. If these particles penetrate our body, they may destroy our DNA or in other words be carcinogenic to the body.

As previously noted, the periodic table is arranged so that elements with similar chemical behaviors are in the same group. ... For example, the elements of Group 1 are known as the alkali metals, Group 2 are the alkaline earth metals, Group 17 are the halogens, and Group 18 are the noble gases.
