List of ten non metals?
Carbon, Nitrogen, Oxygen, Phosphorus, Sulphur, Selenium, Bromine, Iodine, Fluorine and Chlorine (and Astatine and all of the inert gases). If, for whatever reason, you don't like the idea of including Halogens in the list you could replace them with any of the metalloids such as; Boron, Silicon, Germanium, Arsenic, Antimony, Polonium or Tellerium.
Name ten examples non-metals?
nitrogen, oxygen, hydrogen, silicon, neon, phosphorus, argon, bromide, fluorine, carbon
What is the nature of the Se-Cl bond in a molecule of selenium chloride SeCl2 if the electronegativity value of selenium is 2.55 and that of chlorine is 3.16?
The Se-Cl bond in selenium chloride SeCl2 is polar covalent. This is because chlorine has a higher electronegativity than selenium, resulting in an uneven sharing of electrons in the bond. Chlorine, being more electronegative, attracts the shared electrons more towards itself, giving it a partial negative charge and selenium a partial positive charge.
Who invented the first semiconductor diode what it is called as and from which metal it is made up of?
The first modern semiconductor diode was made with germanium. These diodes were invented in ww2 for RADAR. But before that semiconductor diodes were made with galena (lead sulfide), copper oxide, and selenium. I have no idea which was "first".
What is the name for the compound SeF2?
The compound SeF2 is known as selenium difluoride.
Which is the most active nonmetal out of argon chlorine potassium or selenium?
Chlorine is the most active nonmetal out of argon, chlorine, potassium, and selenium. It belongs to the halogen group, which is known for its high reactivity. Chlorine readily reacts with other elements to form compounds.
Which is more reactive Br Se or Cl?
Bromine (Br) is more reactive than chlorine (Cl) and selenium (Se). Bromine has a lower ionization energy and a larger atomic radius compared to chlorine and selenium, making it more willing to participate in chemical reactions.
How many covalent bonds are in the following elements germanium phosphorus selenium chlorine?
Germanium, metalloid with a similar structure to silicon- 4 covalent bonds per germanium atomPhosphorus, the most familiar form is white phosphorus which is molecular, consisting of P4 units, each P atom has 3 covalent bonds, other allotropes are not discrete molecules but all have 3 covalent bonds per P atomSelenium This is molecular in Se8 rings each Se atom has two covalent bondsChlorine this is a diatomic gas with a single covalent bond
Does selenium blow up with chlorine?
It doesn't seem likely. Selenium isn't terribly reactive, and selenium monochloride exists in equilibrium with a different kind of selenium chloride, chlorine gas, and elemental selenium; this indicates that there's not a huge energy difference between the uncombined elements and the compound, as you would expect there to be if they "blew up" when combined.
What are 10 minerals that are non-metals?
Carbon, Hydrogen, Nitrogen, Phosphorus, Oxygen, Sulfur, Selenium, Fluorine, Chlorine and Bromine
Which nonmetallic elements are solids at room temperature?
Carbon, phosphorus, sulfur, and iodine. If metalloids are included, also silicon, germanium, arsenic, selenium, antimony, and tellurium.
Is selenium or sulfur more reactive?
sulfur is more reactive than selenium
Which is a colorless odorless gas with low chemical reactivity based on the periodic table selenium chlorine xenon or carbon?
Xenon as it is a noble gas. Noble gases are inert and do not react with anything. Selenium is a solid Chlorine is a green coloured highly reactive poisonous gas. Carbon is a non-metallic solid.
What compound is formed from selenium and chlorine?
Selenium chloride (SeCl4) is the compound formed from selenium and chlorine. It is a yellowish-red liquid with a pungent odor.
What would you call a germanium atom if you remove two protons?
If you remove two protons from a germanium atom, it would become a selenium atom. This is because germanium has 32 protons, while selenium has 34 protons.
Which has the lower electron affinity germanium or selenium?
Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.
