Where are the electrons found that are involved in ionic or covalent bonding?

Electrons are found in outer shells around the nucleus. The nucleus has protons and neutrons in it. The electrons are in shells or clouds around the nucleus. There are different numbers of electrons in each shell. The first one has two and the second one holds 8 electrons. An ionic bond will transfer electrons where a covalent bond will share electrons in the outer most orbital Hope it helps


Space that represents the average distance that are from the nucleus is called?

Is called a shell. The first shell around the nucleus can hold a maximum of two electrons. While the second shell can hold a maximum of eight electrons.


How many core electrons are in an atom of phosphorus?

this depends on what you mean the "core". there is a nucleus in an atom which is the very centre where the protons and neutrons are but the electrons spin around the nucleus in shells. the first shell has a maximum of 2 the second, a maximum of a 8 and so on.


Where would you expect to find the 6 electrons in an atom of carbon?

All electrons in every atom are located around the nucleus. In carbon atoms there are two electrons in the first principal energy level and four in the second.


What natural phenomena are the basis for time measurements?

scientists use an atom of helium and look at the # of rotations of the electrons around the nucleus. and they determine the second from that


Atoms are positively charged particles that move around electrons?

No. First, atoms have no overall charge (they are electrically neutral) because they have the same number of protons and electrons. Second, there are protons, neutrons and electrons within the atom, and they are collectively termed sub-atomic particles. It is the electrons that move around the nucleus (where the protons and neutrons are).


What is the Bohr model for Lithium?

Lithium is element number 3Its nucleus contains 3 protons and 4 neutrons (Atomic Mass=7) and there are 3 electrons in orbit around the nucleus.Since there can be only 2 electrons in any orbit. the third electron orbits in a second orbital path, further out from the nucleus.


What is the Bohr configuration for chlorine?

17 protons and 18 neutrons in the nucleus 2 electrons in the first orbital. 8 electrons in the second orbital. 7 electrons in the third orbital.


What term is used for the electrons in the outermost shell?

there called valence electrons


Which explains the change in ionization energy that occurs between removing the first and second electrons from an atom?

The attraction between electrons and the atomic nucleus is changed.


What is the central point of an atom called?

It's called a Nucleus The first layer can contain only 2 electrons The second layer, 8 The third layer, 8 and The fourth layer, 18


What are the three basic particles of an atom?

First Answer: The three basic particles of an atom are protons, neutrons and electrons. The proton and neutron comprises of the nucleus of an atom but electrons revolve around the nucleus continuously. The protons are positively charged and electrons are negatively charged while the neutrons are neutral. Thus we can say the whole atom is neutral. Second Answer: 1) Proton (Positive) 2) Neutron (Neutral) 3) Electron (Negative)
