What information about a representative element can you get from just knowing its group number?

What information about a representative element can you get from just knowing its group number?

What information about a representative element can you get from just knowing its group number? The number of electrons it has in the highest occupied energy level.

What does the group number of the representative elements in the periodic table tell you?

The group number of the representative elements = the number of valence electrons.

What is important about the group number of an element?

The Groups All elements in a group have the same number of electrons orbiting the nucleus in the outermost shell. Elements in a group share important chemical characteristics.

How do you identify representative elements?

The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling, and the inner transition metals are the elements where the f orbitals are filling.

What is representative elements give examples?

In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.

What are normal elements give two examples?

Answer: The elements that do not give out any harmful radiations are called Normal Elements. Example: Fluorine (F), Chlorine (Cl), Bromine (Br), etc. Whereas, the elements that give out harmful radiations are called Radioactive Elements….

Which element can kill you?

Polonium-210 While other toxic metals such as mercury and arsenic kill through the interaction of the metal with the body, polonium kills by emitting radiation which shreds sensitive biomolecules, such as DNA, and kills cells….

Which is the most dangerous element?

Plutonium

What is the most dangerous element to humans?

What happens if you drink plutonium?

Not only is it useless to the body, “it is strongly retained by humans when ingested,” primarily lodging in bone and liver cells, where it can release harmful alpha radiation….

What destroys plutonium?

Thorium is therefore the logical choice for plutonium disposal. Plutonium-239 is formed inside a reactor when the isotope uranium-238 captures a neutron and decays.

What happens if you touch uranium?

Because uranium decays by alpha particles, external exposure to uranium is not as dangerous as exposure to other radioactive elements because the skin will block the alpha particles. Ingestion of high concentrations of uranium, however, can cause severe health effects, such as cancer of the bone or liver.

Who has the most plutonium?

The largest stockpiles belonged to the United States with 502 tons of plutonium, Russia with 271 tons and France with 236 tons, according to the report. Stocks of civilian plutonium grow by 70 tons each year, according to the report….
