Q:

Which elements are named after countries?

A:

Quick Answer

Elements that are named after countries are Francium, Gallium and Germanium. Gallium is one of the few metals besides mercury and cesium that is a liquid at room temperature. It was named after the Latin word for France, "Gallia."

Gallium's atomic number is 31, and when it is especially pure, it has a brilliant silver sheen. It doesn't occur freely in nature but is found in ores of zinc and bauxite. Its melting point is so low, about 85.6 degrees Fahrenheit, that it melts in a person's hand. It also alloys with most metals. Gallium is mostly used in electronics, LEDs and high-temperature thermometers.

Francium was also named for France. It is also one of the few elements to have been discovered by a woman. It was discovered by Marguerite Perey in 1939. Francium is formed by the breakdown of actinium and has an atomic number of 87. It is very radioactive and can itself break down into astatine, radium and radon.

Germanium is considered a semi-metal. Its atomic number is 32, and it was named after the country of Germany. It was discovered by Clemens Winkler in 1886 and is largely used for semiconductors and also in infrared instruments.

    How many valence electrons does gallium have?

    A:

    Gallium has three valence electrons. One can find this by looking at the electron configuration, which is Ga:[Ar] 4s2 3d10 4p1. In a chemical reaction, one can lose the electrons in the 4s and 4p subshell, and the total number of electrons in these subshells is three.

  • Q:

    How many neutrons does gallium have?

    A:

    Gallium has 39 neutrons, which is determined by subtracting its atomic number (31) from its atomic weight (70). It also has 31 electrons and 31 protons. Three of gallium's electrons are in its outermost shell and have the ability to be lost or shared.
