If two protons and two neutrons are added to the nucleus of a carbon atom, what nucleus does it become? What will an atom do if it has 1 to 3 valence electrons? In an isotope, which part of an atom changes? What is the electron capture equation? What is the overall charge of an ...
Which ground-state atom has an electron configuration described by the following orbital diagram? Draw an electron dot diagram for beryllium, showing the correct number of valence electrons. What is the condensed electron configuration of O2- ?
The tetrahedral shape is commonly seen in molecules like methane (CH4), where the central carbon atom is bonded to four hydrogen atoms at equal distances. In a trigonal pyramidal molecule like ammonia (NH3), the nitrogen atom has three bonded hydrogen atoms and one lone electron pair, causing...
Neutron has a similar mass to a proton but no charge. The Neutron contributes significantly to the atom's overall mass. 13 Electrons Electron is a negatively charged subatomic particle. Atoms gain or lose Electrons to achieve stability. 10 Neutron Neutron is a neutral subatomic particle located ...
Given the above definition of pH, the fact that a proton is simply a hydrogen atom that has lost its only electron (H+), and using the square bracket notation, we can express the answer to “what is pH?” mathematically: pH = -log10[H+] ...
1) An electron in the K shell is ejected from the atom by an external primary excitation x-ray, creating a vacancy. The K Lines 2) An electron from the L or M shell “jumps in” to fill the vacancy. In the process, it emits a characteristic x-ray unique to this element and in ...
