Answer and Explanation: (d) Cl and Ar have the same ground-state electron configuration.
Which two European countries had the most colonies in Africa? which of the following were effects of european rule in africa? choose three answers..

Which elements have the same electron configuration?

When two different elements have the same electron configuration, they are called isoelectronic.

Can elements have the same ground state configuration?

By ground state it is implied that they are not ionice but neutral, and because every element has a differente number of protons, and therefore electrons, no two atoms can have the same ground state electron configuration.

Can two electrons have the same electron configuration?

Every element has a unique atomic number and therefore a unique number of electrons in its unionized elemental form. You can’t have the same electron configuration with different numbers of electrons.

What is it called when two elements have the same electron configuration?

Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3–, O2–, F–, Ne, Na+, Mg2+, and Al3+ (1s22s22p6).

What is ground state electron configuration?

The ground state electron configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels. The electrons occupying the orbitals of varying energy levels naturally falls towards the lowest energy state or ground state.

What elements have the same electron configuration as neon?

An oxygen atom and a fluorine atom have the same electron configuration as neon.

Is electron configuration the same as ground state electron configuration?

The arrangement of electrons in the atomic orbitals of an atom is called the electron configuration. Electron configurations can be determined using a periodic table. The ground state configuration is the lowest energy, most stable arrangement.

Which two elements both have 2 electrons in an s subshell at the end of their electron configuration?

The electron configuration of a hydrogen atom is spoken out loud as “one-ess-one.” Helium atoms have 2 electrons. Both electrons fit into the 1s subshell because s subshells can hold up to 2 electrons; therefore, the electron configuration for helium atoms is 1s2 (spoken as “one-ess-two”).

Which choice lists two elements with ground state electron configurations that are well known exceptions to the Aufbau principle?

Elements such as copper and chromium are exceptions because their electrons fill and half-fill two subshells, with some electrons in the higher energy level shells.

How do you arrange electron configurations?

Writing Electron Configurations. When writing an electron configuration, first write the energy level (the period), then the subshell to be filled and the superscript, which is the number of electrons in that subshell. The total number of electrons is the atomic number, Z.

How can you tell if two elements are the same?

The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as “isotopes”.

Could the atom and ion of the same element have the same electron configuration?

The term isoelectronic refers to an atom and an ion of a different atom (or two different ions) that have the same electron configuration. The sodium ion is isoelectronic with the neon atom.

Do all electron configurations have same electron affinity?

All electron configurations of an atom have the same electron affinity: Electron affinity increases from top to bottom down the periodic table: Ronald P.
