Electronic configuration: The distribution or arrangement of electrons of a molecule or an atom in molecular or atomic orbitals.
Ground state electron configuration: The distribution of electrons of an atom or molecule around the nucleus with lower levels of energy.
Now, stands for Ruthenium with atomic number 44. It is a metal and thus, has ability to lose electrons and, becomes positively charged ion.
One can write the electronic configuration with the help of atomic number and Afbau principle, Pauli exclusion principle etc.
Ground electronic Configuration is as follows:
Soft Hand notation:
Now, when ruthenium loses two electrons then it becomes , thus electron configuration becomes
Soft Hand notation:
The ground state electronic configuration of Ruthenium is and when it loses two electrons, then electronic configuration becomes ( )
Answer:
A) the number of electrons in the outer shells.
Explanation:
The Bohr's model of the atoms shows that electrons orbits the nucleus in energy levels that are discrete and quantised. Orbital electrons are pulled by the nucleus. The nuclear pull is strongest on the shells closer to the nucleus and weakest as we reach the outermost sphere.
From this model, we see that chemical properties are governed by how much electrons an atom is ready to lose from its outermost shell in which the energy is the lowest. It is the electrons in the outermost shell or valence shell that determines how atoms would behave chemically.
Answer:
Se llaman bioelementos primarios. Los átomos de carbono tienen la capacidad de unirse a otros átomos. Esto permite que tenga lugar la vida y es por eso que el carbono es el bioelemento más importante. Otros elementos químicos se encuentran en los seres vivos; sin embargo, aparecen en pequeñas cantidades.

Answer:
Technician B.
Explanation:
The claim of technician B that the PCM will add fuel if the IAT indicates that the incoming air temperature is cold is correct.
An atom becomes an Ion (a) if it gains one or more electron(s) or (b) if it loses one or more electron(s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation.
