How do you determine the electron configuration of an atom?
Method 1 Assigning Electrons Using a Periodic Table
- Find your atom's atomic number.
- Determine the charge of the atom.
- Memorize the basic list of orbitals.
- Understand electron configuration notation.
- Memorize the order of the orbitals.
- Fill in the orbitals according to the number of electrons in your atom.
What is the ground state configuration of F?
The neutral electronic configuration of F is 1s2 2s2 2p5. When it becomes F+, it means it lose 1 electron (although non common since F is an electronegative atom). Therefore, the electronic configuration of F+ is 1s2 2s2 2p4.

What is electronic configuration?
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. This is also useful for describing the chemical bonds that hold atoms together.
3
What is the Valency of an oxygen atom?
Atoms can either donate or receive electrons only in valence shell. 8 electrons in outermost shell is considered the most stable state of an atom as the shell will be fully occupied. The valency of oxygen is 2 as its electronic configuration is 2,6 and it need 2 electron to complete their octet.
4
Is the element oxygen stable?
Oxygen is element No. 8 on the Periodic Table of Elements. Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth's atmosphere. Because it's all around, oxygen is easy to dismiss as dull and inert; in fact, it's the most reactive of the non-metallic elements.
5
What is the charge of the oxygen ion?
The ionic charge of oxygen is -2. You can tell because oxygen is in group number 6, so it has 6 valence electrons. Since it needs 2 more electrons to become neutral with a full outer shell of 8 electrons, its charge is -2 (since adding electrons gives a negative charge).
6
What is ISO Electronic ions?
Isoelectronic refers to two atoms, ions or molecules that have the same electronic structure and the same number of valence electrons. The term means "equal electric" or "equal charge". Isoelectronic chemical species typically display similar chemical properties.
7
Which element has the greatest electronegativity NP or as?
Thus, fluorine is the most electronegative element, while francium is one of the least electronegative. (Helium, neon, and argon are not listed in the Pauling electronegativity scale, although in the Allred-Rochow scale, helium has the highest electronegativity.)
8
Do the negative ions tend to be metals or nonmetals?
Anions are negatively charged ions and cations are positively charged ions. 2) Anions tend to be __________ and cations tend to be __________. Nonmetals tend to gain electrons and form anions, metals tend to lose electrons and form cations. Aluminum is metal that loses 3 electrons.
9
Which set of orbitals can hold a maximum of 14 electrons?
The five d orbitals can hold up to 10 electrons. Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals. The fourth and higher levels also have an f sublevel, containing seven f orbitals, which can hold a maximum of 14 electrons.
11
Is oxygen anion or cation?
Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. If the oxygen atom loses electrons, it becomes a positively charged cation. Oxygen is most stable as an ion when it gains 2 electrons to become O2-, an anion.
13
What is the name of the group that oxygen is in?
Group 16: The Oxygen Family (The Chalcogens) The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium.
14
What is the net ionic charge of beryllium?
It loses 2 electrons to gain a charge of +2. This gives it the noble gas configuration. See periodic table below.
15
How many bonds can carbon nitrogen oxygen and hydrogen atoms form?
A covalent bond is a strong bond between two non-metal atoms. It consists of a shared pair of electrons. A covalent bond can be represented by a straight line or dot-and-cross diagram. Hydrogen and chlorine can each form one covalent bond, oxygen two bonds, nitrogen three, while carbon can form four bonds.
16
What is the highest occupied energy level of oxygen?
What is it meant by the highest occupied energy level in an atom? The highest occupied energy level in an atom is the electron-containing main energy level with the highest number. Inner-shell electrons are electrons that are not in the highest occupied energy level (sometimes referred to as “Kernel Electrons”). 25.
17
What is the electrical charge of the calcium ion?
An atom of calcium (Ca) has 20 electrons with 2 electrons in the inner shell, 8 in each of the next two and 2 electrons in the outer shell. When the calcium atom loses two electrons to form the calcium ion, what is its net electrical charge? A. plus 1.
18
Which element will have the lower ionization energy?
The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.
19
Is atomic oxygen diamagnetic or paramagnetic?
Let's first check the electron configuration of Oxygen atom. Notice that Molecular Orbital Theory predicts that O2 has two unpaired electrons in 2Px and 2Py degenerate oribitals. Unpaired electrons spin in the same direction as each other, which increases the magnetic field effect. So O2 becomes paramagnetic.
