What is number 16 on the periodic table?
Number 16 on the periodic table is sulfur. It is a non-metal element that is essential for life and is commonly found in minerals, proteins, and amino acids. Sulfur has a variety of industrial uses, including in the production of sulfuric acid.
Does the hardness of water depend upon the metal or non metal ion of the mineral?
The hardness of water depends primarily on the concentration and chemical identities of the metal cations dissolved in the water. The non metal ions dissolved in the water have little effect unless the particular ions are capable of forming coordinate covalent bonds to the metal ions.
What element has the lower atomic number of any group?
Lithium is the element with the lowest atomic number in Group 1 (alkali metals), while hydrogen is the element with the lowest atomic number in Group 17 (halogens) and Group 18 (noble gases).
What household objects have a chlorine compound in it?
Household bleach is a common household object that contains a chlorine compound called sodium hypochlorite. Pool cleaning products and some water purification tablets may also contain chlorine compounds like calcium hypochlorite. Some disinfectants and toilet bowl cleaners contain chlorinated compounds like trichloroisocyanuric acid.
Why is plutonium part of the actinides family group?
Plutonium is part of the actinides family group because it has similar chemical properties to other elements in the actinide series. It has a partially filled 5f orbital, which contributes to its characteristic behavior and placement on the periodic table. Additionally, the actinides share properties related to their electron configuration and position within the periodic table.
How do the elements of the whole periodic table relate to the lifecycle of a star?
A star is made up of Hydrogen and Helium, (the Helium coming from the fusion of Hydrogen atoms). When a star goes super nova, it is so hot that it fuses together gases so rapidly that it creates all of the elements on the periodic table.
If the atom is atomically neutral (meaning that it does not hold a charge and it's not a cation or an anion), then the number of electrons and protons in an atom will be the same. If they do hold a charge (say if it is an anion), then it would have an extra electron. If it was positively charged, then an electron would be lost.
How many protons and neutrons are there in the sulfur 36 isotope?
The sulfur atom has 16 protons and 16 electrons.
The three stable isotopes of sulfur differ in their neutron number:
Isotopes with mass number -32, -33 or -34 have 16, 17 or 18 neutrons respectively. The isotope with mass number 32 is the most abundant natural isotope.
What isotope has 16 protons and 15 neutrons?
The isotope with 16 protons and 15 neutrons is oxygen-31.
What is a row of stables with living quarters above called?
A row of stables with living quarters above is commonly referred to as a "stable block" or a "stable complex." These structures are designed to provide both accommodation for horses and living space for the caretakers or owners.
Why are chlorine and chloride the same on the periodic table?
Position on the periodic table is determined by the number of protons in the nucleus. This number is 17 for both neutral chlorine atoms and chloride anions. Because the chloride anion has one more electron than it has protons, the anion has one negative electrical charge.
What is the mass of a molecule of copper oxide?
The mass of a molecule of copper oxide is the sum of the atomic masses of copper (Cu) and oxygen (O) in the molecule. The molecular formula of copper oxide is CuO, so the mass would be the atomic mass of Cu (63.55 g/mol) plus the atomic mass of O (16.00 g/mol), which equals 79.55 g/mol.
What is a row of stables called?
A row of stables is typically referred to as a "stable block" or a "stable row." It is a series of individual stables built together in a row or block formation.
What are the similarities between the elements in group 0 in the periodic table?
Elements in group 0 (also known as group 18) of the periodic table, called noble gases, share the characteristic of having a full outer electron shell, making them stable and unreactive. They exist as single atoms rather than forming molecules, and have low boiling and melting points due to weak interatomic forces.
What do each of the letters mean on the periodic table?
they are not mere letters.it is a shorthand method of representing the basic and mounted up elements of chemistry...an essential tool for every chemist.
How many electrons does the isotope sulfur-36 have?
Atomic number of sulfur = Number of protons = Number of electrons = 16
Is neon essential for human survival?
"Neon is a chemically inert gas. An atom of neon will not combine with other atoms to produce chemical compounds. This means that it really serves no known biological function.
Neon does have scientific and commercial uses, the best known of which is in neon lights for advertising. It is also used in vacuum tubes, television tubes, and lasers, among other things."
Where does neptunium fit on the periodic table?
Neptunium is a radioactive actinide element with the atomic number 93. It is situated in the actinide series of the periodic table, which is the row below the lanthanide series, between uranium and plutonium.
No, poop is not an element. Elements are substances that cannot be broken down chemically into simpler substances, while poop is a mixture of waste products that have been digested and eliminated by an organism.
Did dmitry mendeleev credited with developing the first periodic table?
Yes, Dmitry Mendeleev is credited with developing the first version of the periodic table in 1869. He organized the elements based on their atomic mass and properties, and left gaps for elements that had not yet been discovered.
Which group on the periodic table would not be reactive chemically?
The noble gases, column 18 or VIII of a periodic table, are the least reactive. However, in the last few decades, compounds of at least the heavier members of this group have in fact been made. Therefore, there is no longer any entire group on the periodic table that is totally unreactive chemically.
What is requisite for good table?
A good table should be sturdy and stable, with legs securely attached. It should be properly sized for the intended use, with enough surface area to comfortably accommodate the items to be placed on it. A durable and easy-to-clean surface material is also important for longevity.
What is the main characteristic of family 18 elements?
The main characteristic of family 18 elements is that they are known as the noble gases. They have a full outer electron shell, making them stable and unreactive. They are colorless, odorless, and tasteless gases at room temperature.
Why is oxygen more reactive compared to polonium?
The electronegativity of oxygen is much higher than that of polonium, even though their valence electron configurations are superficially the same, because an oxygen atom is much smaller than a polonium atom, so that accepted additional electrons are much closer to the electrically attractive nucleus of an oxygen atom than of a polonium atom.
What is the total number of subatomic particles in sulfur?
In order to answer this question, a particular isotope of sulfur must be considered. The most common isotope is sulfur-32, which has 16 protons, 16 neutrons, and 16 electrons for a total of 48.
