Who discovered niobium?
Niobium was the first of these two elements to be discovered. In 1801, Charles Hatchett (1765-1847), an English chemist, analysed a specimen of an unknown mineral from the collection of the British Museum in London.
Where is niobium found?
Niobium has no known biological role. The main source of this element is the mineral columbite. This mineral also contains tantalum and the two elements are mined together. Columbite is found in Canada, Brazil, Australia, Nigeria and elsewhere.
What is the atomic number of an atom that has an atomic mass of 40 and has 22 neutrons?
Argon has 18 protons and 22 neutrons in its nucleus giving it an Atomic Number of 18 and an atomic mass of 40. Argon is a Noble Gas.
Is HF a element?
hafnium (Hf), chemical element (atomic number 72), metal of Group 4 (IVb) of the periodic table. It is a ductile metal with a brilliant silvery lustre.
What is Neon’s atomic number?

What is zirconium made of?
Zirconium, symbol Zr on the Periodic Table, is a metal most often found in and extracted from the silicate mineral zirconium silicate and the oxide mineral baddeleyite.
What is the symbol of nickel?
nickel (Ni), chemical element, ferromagnetic metal of Group 10 (VIIIb) of the periodic table, markedly resistant to oxidation and corrosion.
Is bromine a metal?
Smelly element No. 35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature, and one of only two elements (the other being mercury) that is liquid at room temperature and pressure.
How many protons are in copper?
All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons (Figure 4).
When was iron found?
Archeologists believe that iron was discovered by the Hittites of ancient Egypt somewhere between 5000 and 3000 BCE. During this time, they hammered or pounded the metal to create tools and weapons.
Which element has the largest atomic radius?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
How many electrons does K 40 have?
Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons. Traces of K-40 are found in all potassium, and it is the most common radioisotope in the human body.
How many protons are in zinc?
Explanation: For Zn , Z=30 .. i.e. the nucleus with 30 nuclear protons is characterized as zinc… But we got Zn2+ …and this ion necessarily has 28 electrons…how many in the NEUTRAL metal?
What is the atomic number of zirconium 39?
Zirconium is a chemical element with the symbol Zr and atomic number 40.
Which of these elements has an electron configuration of KR 5s 2?
Potassium has nineteen electrons, one more than the noble gas argon, so its configuration could be written as [Ar]4s1. In a similar fashion, strontium has two more electrons than the noble gas krypton, which would allow us to write its electrons distribution as [Kr]5s2 .
