What is an Zirconium (Its an element) . in your own words but be more detailed about what you say. If you don't know it, look it up and reword the meaning.

Zirconium is a silver-gray transition metal, a type of element that is malleable and ductile and easily forms stable compounds. It is also highly resistant to corrosion. Zirconium and its alloys have been used for centuries in a wide variety of ways.  

It is commonly used in corrosive environments. Zirconium alloys can be found in pipes, fittings, and heat exchangers, according to Chemicool. Zirconium is also used in steel alloys, colored glazes, bricks, ceramics, abrasives, flashbulbs, lamp filaments, artificial gemstones, and some deodorants, according to Minerals Education Coalition.

Other uses for zirconium include catalytic converters, furnace bricks, lab crucibles, surgical instruments, television glass, removing residual gases from vacuum tubes, and as a hardening agent in alloys such as steel, according to Lenntech. Also, zirconium carbonate is used to treat poison ivy, according to the Jefferson Laboratory.

Zirconium has been found in S-type stars, the sun, meteorites, and in lunar rocks, according to the Los Alamos National Laboratory. Lunar rocks appear to have a surprisingly high zircon content compared to terrestrial rocks, according to an analysis of lunar rock samples from the various Apollo missions.  

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the answer is true. hope it .
