What does the atomic number of an element tell you about the element? A certain element has its outermost electron in a 2s subshell. It has valence +1 because it has 1 more electrons than a certain noble gas. What element is it? Express your answer using its one- or two Which atom i...
An atom of an element X has 2 electrons in its N shell. Write the formula of its chloride. View Solution An element X has atomic number 17 and has mass no. 37. Draw its orbital structure and state the position of X in the periodic-table. View Solution Identify the group and valen...
53K What are electron configuration orbitals? Learn about the s, p, and d orbital electrons, and use the periodic table to understand orbitals and placement. Related to this QuestionWhich element has the excited state electron configuration 1s22s22p43s1? Which element is a transuranium element...
Now let us add a pentavalent element like arsenic in that germanium semiconductor. The arsenic has five valence electrons since it is pentavalent. The four of the valence electrons of each arsenic atoms take part in the creation of covalent bonds with four neighbouring germanium atoms. In this ...
Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. Valence electrons are of crucial importance because they lend deep insight into an element’s chemical properties: whether it is electronegative or el

In any atom, like charges repel one another, and opposite charges attract one another. This is why two protons repel each other and so do two electrons, but a proton and an electron attract each other. In an element, the numbers of electrons and protons are equal. Moreover, since they...

Electrons Plural of electron Neutron An elementary particle with 0 charge and mass about equal to a proton; enters into the structure of the atomic nucleus Common Curiosities What charge does a Neutron have? A Neutron is neutral and has no charge. 15 How do Electrons influence an element's ...
What happens if an atom has more electrons than protons? It becomes a negatively charged ion, called an anion. 6 Why are protons crucial to an element's identity? Because the number of protons determines the atomic number and thus the element's identity. 4 What role do protons play in th...
