Tungsten (W) has an atomic number of 74. This number is high compared to the whole Periodic Table. There are only 18 more natural elements with a higher number.
What else can I help you with?
Are Tungsten watches considered high end?
Tungsten watches are for the most part considered high end due to their starting price point for some being well above $300 for most watches. However not all tungsten watches are high class and can go for as low as $8 as it's mostly brand names and not materials.
Does a small atomic radius correspond with a high or low electronegativity?
A small atomic radius corresponds more closely to a low electronegativity.
What can an element's atomic number tell you about its state of matter?
An element's atomic number tells you the number of protons in the nucleus of its atoms. This, in turn, can help predict its state of matter at room temperature. Elements with low atomic numbers are typically gases, while those with higher atomic numbers are solids or liquids.
What is the lightest element metal?
Lithium is the lightest element metal with a relative atomic mass of 7 (3 protons, 4 neutrons).
When the elements on the periodic table are arranged by increasung atomic number the atomic mass generally increases as the atomic number increases. for some elements however the atomic mass of the el?
It is difficult to be sure what the question is about because it has been truncated.However, it is true that the atomic mass (or standard atomic weights) increases with atomin number. There are, of course, isotopes of elements with a low atomic number which are heavier than atoms of higher atomic number. But there are some examples where the average mass is not in the expected sequence.
What is pure tungsten?
As a high performance material, pure tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance and high modulus of elasticity.
What are low and high z materials?
In materials science, "low z" refers to elements with low atomic number, such as carbon, silicon, and oxygen. "High z" materials, on the other hand, refer to elements with high atomic number, such as lead, uranium, and gold. Low z materials are typically lighter and more abundant, while high z materials are denser and often have unique properties due to their higher atomic number.
Why might a substance have a high or low density?
Is it to do with the atomic number of a particular element or the volume of the element.
The target element of an x-ray machine must have a high enough atomic number so that?
The target element of an x-ray machine must have a high enough atomic number so that it has a high number of orbitalelectrons for the incident electrons to interact with. The higher the atomic number, the more orbital electrons that element will have. It must also have a high melting point and low rate of evaporation.
Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
Is tungsten a good conductor at a low or high resistance?
Tungsten is a good conductor with high resistance. It is commonly used in applications that require high resistance to heat and wear, such as light bulb filaments, because it can maintain its structural integrity at high temperatures.
What is the atomic number of helium and how does it relate to its properties?
The atomic number of helium is 2. This number indicates the number of protons in the nucleus of a helium atom. The atomic number of an element determines its chemical properties, such as its reactivity and bonding behavior. Helium's atomic number of 2 means it has a stable configuration, making it a noble gas with low reactivity and high stability.
Are Tungsten watches considered high end?
Tungsten watches are for the most part considered high end due to their starting price point for some being well above $300 for most watches. However not all tungsten watches are high class and can go for as low as $8 as it's mostly brand names and not materials.
Is tungsten carbide a brittle material?
Yes, tungsten carbide is considered a brittle material due to its high hardness and low ductility, making it prone to cracking or breaking under stress.
Is tungsten carbide brittle and prone to fracturing under certain conditions?
Yes, tungsten carbide is brittle and can fracture under certain conditions due to its high hardness and low ductility.
Does a small atomic radius correspond with a high or low electronegativity?
A small atomic radius corresponds more closely to a low electronegativity.
Is tungsten magnetic or non-magnetic?
Tungsten carbide products are often made from tungsten carbide powder cemented with another metal. This metal is often cobalt or nickel which is magnetic. 6% cobalt by weight is a typical percentage. Cobalt cemented tungsten carbide is magnetic enough to be picked up with a strong magnet. Tungsten carbide by itself would have very low to no ferromagnetic properties.
