The arrangement of electrons in an atom is called?

A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.


How many electrons must a magnesium gain or lose to achieve electron configuration?

Well, isn't that a happy little question! Magnesium has 12 electrons, and to achieve a stable electron configuration like the noble gas neon, it can lose 2 electrons. By doing this, magnesium becomes positively charged and forms a stable ionic bond with other elements. Just remember, there are no mistakes, only happy little accidents in the world of chemistry!


Is oxygen a radical?

Oxygen itself is not a radical. A radical is a species with at least one unpaired electron, whereas oxygen typically exists as O2, which has paired electrons. However, oxygen can form radicals in certain conditions, such as during cellular respiration or in the presence of certain pollutants.


What non-metals are attracted to magnets?

Non-metals like oxygen and sulfur are generally not attracted to magnets due to their lack of unpaired electrons that are necessary for magnetism. Only certain metals, such as iron, nickel, and cobalt, exhibit magnetic properties.


How many sublevels are occupied in an atom of sulfur in the ground state?

there is only one unpaired electron in copper


What is an electron configuration and what does it tell you about an element?

The arrangement of electrons in various shells around the nucleus of a atom is called its electronic configuration.If the electrons in the last shell or the valence shell are between 1 to 3 then the element and if they are between l4 to 7 then the element in a non metal.


What is the electrons location?

Electrons orbit the nucleus of an atom. The exact location of a specific electron, however, can not be known for certain. The general area where the electron might be found is in its orbital.


Is uranium more likely to lose or gain electrons?

Uranium loose electrons becoming a cation.


How are electrons in atom organized?

Electrons occupied certain discrete energy levels around the nucleus.


What element has 10 electrons when it form an anion with a 2 negative charge.?

The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.


Why are certain materials magnetic?

Certain materials are magnetic because their atoms have unpaired electrons that create a magnetic field. This magnetic field allows the material to attract or repel other magnetic materials.


What is it about certain materials that makes them attracted to a magnet?

Certain materials are attracted to magnets because they have unpaired electrons that align in the presence of a magnetic field, creating a magnetic force that pulls them towards the magnet.
