What is the electron configuration?
The arrangement of the electrons in an atom is known as its electron configuration.
What is an atom's electron configuration?
The arrangement of electrons in an atom.
What property of an atom determines what element it is?
Much of the nature of an atom is determined by the configuration of its electrons. The configuration controls how freely it can bond, how charged the atom is, how stable it is, and other atomic properties.
How many electrons will a calcium atom Ca lose in order to get a noble gas configuration?
Calcium will lose two electrons to gain the noble gas configuration of Argon.
What is the electron configuration of a neutral atom of oxygen?
Orbital 'fill up' of Oxygen (atom number 8) (K) = 2 electrons (L) = 6 electrons
What is the electron configuration?
The arrangement of the electrons in an atom is known as its electron configuration.
What does the configuration of an atom shows?
The configuration of an atom shows the arrangement of electrons, and also if the charge is positive or negative.
How many d electrons are there in an atom of iron?
The electron configuration for this atom is 1s22s22p63s23p64s23d64s2. There are 6 d electrons.
About the electron configuration?
Electron configuration for an atom is the distribution of electrons on atomic orbitals.
The element fluorine has 9 electrons which is the electron configuration for an atom of fluorine?
The electron configuration for an atom of fluorine is [He]2s2.2p5.
What is the electron configuration for an atom that has 15 electrons?
1s22s22p63s23p3
How many electrons has O?
An atom of oxygen has 8 electrons, in the configuration 2,6.
What is an atom's electron configuration?
The arrangement of electrons in an atom.
How many valence electrons does a chlorine atom have if its electron configuration is Ne3s23p5?
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
How many electrons are there in the neutral atom which has the ground state outer electron configuration of 4s2?
Calcium has the electron configuration [Ar]4s2; the neutral atom of calcium has 20 electrons.
What is the valence electrons configuration for the phosphorus atom?
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
How may electrons does each atom of carbon have?
A neutral carbon atom has 6 electrons in the following configuration: 1s2 2s2 2p2
