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 current a flow of electrons?
In general, yes, we normally think of the movement of electrons (electron flow) as electric current.
What is the location of electrons?
Around the atomic nucleus, on electron shells.
What is the general electron configuration for alkaline earth metals?
2 electrons in the outermost shell.
Why the electron affinities of beryllium and nitrogen are positive?
In general, elements attract electrons because they have positively charged nuclei, and although they also have negatively charged electron shells, the electrons are very mobile and they adjust themselves so that they have the minimum effect on other electrons while remaining as close as possible to the nucleus (a constant balancing act). The specific degree to which a given element will attract electrons is strongly influenced by the kind of electron configuration that the element has. Nitrogen, which can form a complete outer shell by acquiring another 3 electrons, has a much stronger attraction for electrons than beryllium has, since beryllium can more easily get to a complete outer shell by losing electrons than it can by gaining them.
Why do electrons stick together so well?
In general, electrons do not stick together well at all. In fact each electron repels every other electron. Electrons pack into high densities in atoms because each electron is attracted to the positive charge of the atom's nucleus more strongly than it is repelled by the other electrons in the atom.
What does ionization energy remove from an atom of an element?
Ionization energy and electron affinity for cations and anions, respectively.
Can the exact location of an electron be known at any time y?
The exact location of an electron can not be known. Electrons' locations can be merely estimated. Electron "clouds" or orbitals are general areas where an electron is likely to be found. There is always uncertainty as to where the electron actually is.
What are atoms that have an electrical charge due to gain or loss of electrons?
A cation for an atom that has lost an electron and is now positive and an anion for an atom that gained an electron and is now negative.The general term for an atom with a different number of electrons than protons is an ion.
Why does reactivity of the halogens decrease down the group?
As it go down the group, the distance between the nucleus (+ve) and the last electron (-ve) becomes smaller No: BIGGER.Therefore the electrons are held in the atom very tightly more loosely by a strong weakening force from the nucleus.So, it is said as the reactivityDEcreases down the group of NON-metals which gain stronger their electrons andINcreases down the group of metals which loose those electrons.
The general idea behind the electron transport chain is?
That ADP is converted to ATP and also that electrons are shuttled down the chin of electron acceptors, until molecular oxygen acts as the final electon acceptor.
What are the 2 regions of the atom?
In general, the nucleus and the electron cloud are the two distinct features of the volume of the atom. The nucleus is home to the proton(s) and whatever neutrons are present, and the electron cloud is where the electrons all hang out. The nucleus, with its protons and neutrons, has most of an atom's mass concentrated there. The electrons are relatively far away, and the orbits they describe give the atom its "shape" by defining its volume in space.
