Why is lathanide and actinide not part of the periodic table?
Besides the periodic table, an electron chart of the elements exists. The periodic table shows the broad outline. The electron chart goes into greater detail. The periodic table lists elements according to electrons in their outer shell. As elements get more massive they get more protons and electrons. Each time they add a proton, they jump one notch in the periodic table. When they add the electron, it is a valence electron and it affects the chemical properties. There comes a point when elements start adding electrons when the electrons are not added to the outer shell with the other electrons in the valence shell. The chemical properties do not change as the elements get heavier. It is extremely difficult to use chemistry to separate the elements in that group. If you had an electron chart, you would see the electrons followed a different pattern. That is why the lanthanides and actinides are set apart from the other elements on the periodic table. According to their chemical properties, they would all need to be put into one box.
On topographic maps contour lines that are far apart indicate?
On topographic maps, contour lines that are far apart indicate gentle slopes or gradual changes in elevation. The farther apart the contour lines, the flatter the terrain.
What happens when warm air molecules move farther apart?
When warm air molecules move farther apart, the air becomes less dense because there is more space between the molecules. This causes the warm air to rise, as it is lighter than the surrounding cooler air. As the warm air rises, it cools and can lead to cloud formation and possibly precipitation.
Are Europe and north America drifting closer together or farther apart?
Europe and North America are drifting farther apart at a rate of a few centimeters per year due to the movement of tectonic plates. This movement results from the spreading of the Atlantic Ocean, causing the two continents to move away from each other over time.
True or false the farther apart waves are the greater their wavelength?
True. Waves with a greater wavelength will have a longer distance between each wave crest compared to waves with a shorter wavelength.
Which elements are apart of sodiums family in the periodic table?
Sodium, Na, is in group 1 on the periodic table. The elements in group1 are the elements in that vertical column, which are Li,Na,K,Rb,Cs,Fr.
What are the byproducts of Supernovae?
All the elements of the periodic table apart from hydrogen and helium are synthesised in the explosion of a supernova.
Can all elements on the periodic table be classified as metals or nonmetals explain?
No, all elements on the periodic table cannot be classified as either metals or nonmetals. Some elements, known as metalloids, have properties that fall between those of metals and nonmetals. These elements are typically found along the zigzag line on the periodic table.
What is it called when waves are farther apart?
When waves are farther apart, it is referred to as having a longer wavelength.
What is lanthandes?
The Lanthanides consist of the elements in the f-block of period six in the periodic table. While these metals can be considered transition metals, they have properties that set them apart from the rest of the elements.
Would the Periodic table of Earth?
The periodic table is based on the periodic law, which is a universal law of nature. Apart from cosmetic things like a different language, different symbols, and different media, the periodic table discovered by any alien culture would be identical to that of the Earth.
Can all elements on the periodic table be classified as metals or non metals Explain?
No, all elements on the periodic table cannot be classified as metals or non-metals. The periodic table includes metals, non-metals, and metalloids, which have properties of both metals and non-metals. Elements are classified based on their physical and chemical properties, such as conductivity, reactivity, and appearance.
What makes noble gases unique compared to other elements in the periodic table?
Noble gases are unique because they are very stable and do not easily react with other elements to form compounds. They have a full outer electron shell, making them very unreactive and inert. This stability sets them apart from other elements in the periodic table.
Are all of the elements on the periodic table?
Sort of. On the one hand, particle physicists can create almost arbitrarily heavy nuclei, and these will continue to be added onto the end of the periodic table and named after important people as they are created. However, all the stable elements, ie all those that last more than a tiny fraction of a second before falling apart into something else, most likely are already on the periodic table, and it's only really these ones that are relevant to most of science.
How many known elements were published on the periodic table?
In the original periodic table by Dmitri Mendeleev, there were 62 known elements listed. What set Mendeleev's table apart from others around the same time is that he allowed gaps for elements that completed trends, and also included some elements that had not been completely confirmed at the time. At current, there are 118 elements in the periodic table, 6 of which have not yet been given an IUPAC name. All of the elements from Americium onwards are artificial, and not found anywhere in nature. Some other radioactive elements are present in nature, usually as decay products from higher radioactive elements.
What other inventions did Dimitri Mendeleev have?
His most famous invention was the Periodic Table of Elements. He also had many more!
What happens when particles of a material move farther?
When particles of a material move farther apart, it explodes.
