What is the first element of the scientific method?
Hypothesis
In what year was the element oxygen first identified?
1772
What element is known as Zn?
Just zinc. Chemical symbol Zn, atomic number 30 and the first of the elements in group 12 of the periodic table.
What is the first element that needs the third shell?
Sodium, assuming "first" means "first in the periodic table", i.e. the one with fewest electrons per atom. The first shell holds 2 electrons, and the second holds another 8. So the element with atomic number 11 is the first one to need the third shell, and that's sodium.
Testing the Electric Hot Water Heater Element?
If the water from the faucet is tepid or cold, it might be time to check the electric hot water heater element. Electric hot water heaters are equipped with two heater elements that heat water. They do so through an electrical current the goes through the element. The lower element does the hard work and is most likely to be the first that burns out. Turn off the electricity, and disconnect the wires at the heating element terminals. Set the multimeter to read resistance. Touch the clips on each terminal of the element. If the Ohmmeter doesn't budge, the element is shot.
What family does the element lutetium belong in?
Lutetium is one of the first inner transition series metals, sometimes called "lanthanides" because all of them have chemistry very similar to that of lanthanum, the first member of the series.
What is the name of two series of inner Transition elements?
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
What is the first number in the lanthanide series?
57
What is a lanthanide element?
Lanthanides are any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57 - 71). With scandium and yttrium, they make up the rare earth metals. Their atoms have similar configurations and similar physical and chemical behaviour; the most common valences are 3 and 4.
The element lanthanum is in what section on the periodic table of elements?
The element Lanthanum (La) is a transition metal and the first of the 'Lanthanides'.
What family does the element actinium belong to?
Actinium belongs to the actinide family, which is a group of elements located in the periodic table below the lanthanide series. These elements are all radioactive and have important applications in nuclear energy and medicine.
What is the first member of the noble gases and the second most abundent element in the universe?
Helium is the first member and the most abundent element in the known universe
Lanthanide and actinide series do not start with lanthanum and actinium explain?
Lets take the Lanthanides as an example. Lanthanum has its 5d sublevel filled before its 4f, even though the 4f is lower in energy and should, by the Aufbau Principle, be filled first. However, this is an exception because it happens to be the most stable configuration. It has one electron in the 5d sublevel and none in the 4f, and since it has no "f" electrons, it cannot be part of the f-bar's upper row (the Lanthanide series). The Lanthanides themselves will each also have one electron in the 5d sublevel, and the first element will also have one in the 4f sublevel. This trend will continue for all 14, and thus the 4f sublevel is filled. Hafnium, the element immediately after the last Lanthanide, will resume filling the 5d sublevel as normal, with two electrons in it and a completely filled 4f sublevel. The anomaly does not really change much; after all, if the valence electron in Lanthanum were not in the 5d sublevel and instead in the 4f, it would start off the Lanthanide series, there would be 14, and it would simply end one element before it normally does. The numbers all add up, in any case, and this is the natural order of things. For Actinides, replace the word Lanthanum with Actinium, Hafnium with Darmstadtium, 5d with 6d, and 4f with 5f. Everything works out perfectly; all the confusion is just caused by the stubborn little electron who doesn't want to be the first f-block element (and so he moves up into 5d, and stays there while the others take their appropiate places, which are moved one up thanks to his desire to maintain stability).
Is U a lanthanoid a series element?
yes, it is part of the first row called the lanthanoid series, is made up of soft, malleable metals that have a high luster and conductivity.This is incorrect. Uranium is an Actinoid series element, not a lathanoid series element.
