How many electrons must a magnesium gain or lose to achieve electron configuration?
The way the question is worded makes little. A magnesium atom has an electron configuration whether it is negatively charged, neutral, or positively charged.Electron configuration is not a fixed definition that only allows for one certain number of electrons in order for it to "be achieved," simply the fact that it has any electrons at all means it must have an electron configuration.In its neutral state its electron configuration is: 1s22s22p63s2 (or abbreviated: [Ne]3s2).
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 location of electrons?
Around the atomic nucleus, on electron shells.
3d electrons on Fe?
The 3d sub-level has 5 orbitals, and therefore space for a total of 10 electrons. Excluding certain hyper-valent bonding scenarios, the first element with electrons to occupy the 3d sub-level is scandium (Sc).
The region of space where electrons of a certain energy move about the nucleus of an atom?
You think probable to the electron clouds.

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.
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.

What three facts about the elements can be derived from the periodic table?
You can find out what groups certain elements are in, and find there relative atomic masses. You can also find outy how reacticve they aRE AND HOW MANY ELECTRONS NEUTRONS AND PROTONS ARE IN CERTAIN ELEMENTS
What does the electron gun do in a crt monitor?
electron gun just fires electrons with certain energy so that when the electrons strikes on the pixels of the screen then they glow up with certain color... this color is defined according to the energy of electron..i.e electrons with high energy will lit up blue &with low energy lit up red color. energy=frequency*plank's constant(n)...
What is the atoms electron cloud?
The distribution of electron around an atom in various shells is sometimes referred to as electron cloud. If there are more electrons in certain space around the atom, that space is said to have a denser electron cloud.
3d electrons on Fe?
The 3d sub-level has 5 orbitals, and therefore space for a total of 10 electrons. Excluding certain hyper-valent bonding scenarios, the first element with electrons to occupy the 3d sub-level is scandium (Sc).
How many electron clouds does carbon?
Each level of the electron couds hold a certain number of electrons. The first holds 2, the second 8, the third 8.(This is the rule used for an electron cloud.) You can base the number of rings by the number of electrons in the particular element.
The region of space where electrons of a certain energy move about the nucleus of an atom?
You think probable to the electron clouds.
What region is occupied by electrons moving around the neucleus of an atom?
The region surrounding the nucleus in which electrons with certain energy move is called the orbital. It refers to a bit of space where there is a 95% chance of finding an electron.
