They aren't in the same group. Iron is in group 8, cobalt is in group 9, and nickel is in group 10. However there is often a special marking around these elements on a Periodic Table that labels these as the "iron triad." These are the magnetic elements on the periodic table.
Yes. They are all in the transition metals group. Because they are all magnetic.
Because iron, cobalt and nickel have such simularities that they are together.
Their electron configuration of the outer most shell (valence shell) is the same:
C : -- 2s2 2p2
Pb: -- -- -- -- -- 6s2 6p2
metalloids,nonmetals and nonmetalloids.
because each one is a type of atom, that is, the smallest part of a pure substance that still has the same properties.
They are both transition metals.
Yes,
iron, nickel, cobalt, some rare earth metals and some of their alloys (e.g., Alnico), and some naturally occurring minerals such as lodestone. the same as with a normal magnet just that you can control the power
Period 4: iron (Fe), cobalt (Co), nickel (Ni).
probably since the first part of the earths birth is the Earth's inner core which is a solid iron-nickel alloy with a few trace elements. The outer core is roughly the same in composition, but in liquid form. The Earth's outer core is most likely made up of an iron-nickel alloy while the inner core mostly iron and a bit of nickel and cobalt. This is due to inferences that iron, cobalt and nickel are denser than other materials found at different levels in the structure of Earth, such as magnesium in the mantle. the mantle is made up of molten and burnt rocks..we live on the earths crust which makes it warm or cold in different places .So marble should be rock that cooled up in the earths crust ,that should be in thecrust of earth for millions of years
Outer and inner core are made of the same thing: iron and nickel
they are both part of the earth
iron, nickel, cobalt, some rare earth metals and some of their alloys (e.g., Alnico), and some naturally occurring minerals such as lodestone. the same as with a normal magnet just that you can control the power
Yes. They are all in the transition metals group. Because they are all magnetic.
It attracts the exact same thing as ordinary magnets do. Ex.: steel, iron, cobalt, and nickel
Period 4: iron (Fe), cobalt (Co), nickel (Ni).
Nickel and iron or iron and nickel (is the same)
Yes, a scrap heap magnet works in the exact same way as a normal magnet but on a large scale. Iron, Cobalt and Nickel are all magnetic elements.
There are three main magnetic metals, here they are, with densities in kg / cubic metre Iron 7850 Cobalt 8746 Nickel 8800 So, for same volume, iron is the lightest
Iron (or, from a physics standpoint, ferrous or, more probably, ferromagnetic metal). Magnets attract magnetic material, and there are only a few ferrous materials around. The word ferrous is from the word ferrum, which is the Latin word for iron. The chemical symbol for iron is Fe and it comes from the same source. Iron, cobalt and nickel are the "big three" ferromagnetic materials, but gadolinium and dysprosium also exhibit ferromagnetic properties. Certainly compounds and mixtures that include these elements are (usually) ferromagnetic. Wikipedia has some good info posted in their article on ferromagnetism. Need a link? You got it.
because i learned it in class and my teacher told the class that magnets only stick to iron or steel and teachers DO NOT LIE.
An object that attracts material containing iron and always faces the same direction when moving freely is lodestone. ---- Nickel and cobalt are two other metals, in addition to iron, that display this type of magnetism. If you wish more information it is available on the wikipedia article entitled 'magnet'.
Cobalt, element 27, is a transition metal, and it is in Group 9 on the periodic table. Cobalt is critical to industry. It is used in making a number of different metal alloys, as a catalyst, and is used in compounds to manufacture coloring agents. It is a tough, lustrous silver-white magnetic metallic element that is related to and occurs with iron and nickel and is used especially in alloys. In nutrition, cobalt is a trace mineral that forms part of the structure of vitamin B12. The total amount of cobalt in your body is 1.1 mg. It is readily absorbed from your small intestine, and your liver stores most of your body's cobalt. Cobalt is essential to humans as well as to animals. It is the main constituent of cobalamin, also known as vitamin B12, that is basically cobalt's biological reservoir. The activity and function of cobalt is essentially the same as vitamin B12. Cobalt also assists in regulating enzymes that break down proteins, including casein, phosvitin, and other phosphoproteins. Along with nickel and manganese, cobalt can be a good alternative for zinc in some enzymes.
Newlands Law of Octaves has many limitations, which are discussed below.1. This law was not applicable throughout the arrangement. It was applicable only till calcium.2. Newlands assumed that only 56 elements would exist in nature and believed that no more elements would be discovered. However, several elements were discovered in the following years. These elements did not follow the Law of Octaves.3. The positions of cobalt and nickel could not be explained according to Newlands Law of Octaves. He kept cobalt and nickel in the same slot. They were also placed in the same column as fluorine and chlorine, which have completely different properties.4. The properties of iron are similar to those of cobalt and nickel. However, iron was placed away from them in a different column.
