Copper and Chromium have 1 electron in the 4s subshell, and 5 and 10 in the 3d subshell respectively. You needn't know beyond that until University.
If you use high-end equipment such as electron microscopes, you can detect the amount of electrons are in an atom and therefore identify that element. Examples; 1 electron - Hydrogen 8 electrons - Oxygen 111 electrons - Roentgenium
The electronic configuration of an element gives an idea about its reactivity. The elements having a completely filled outermost orbit (or shell) will be chemically inert (non-reactive). For example, the outermost shell in the case of helium (He), neon (Ne) and argon (Ar) are completely filled as shown below. As a result, helium, neon, and argon are chemically inactive (or inert). These elements do not form compounds with other elements. Because of this chemical inactivity, these gases are called as noble gases (earlier these were called inert gases). The elements containing only one or seven electrons in their outermost shell show greater chemical reactivity, i.e., such elements react very fast with other elements. For examples, sodium and chlorine having the follows electronic configurations are highly reactive. Sodium 2, 8, 1 ---- Here, the outermost shell has been one one electron: one more than the completely filled shell. Chlorine 2, 8, 7 ----- Here, the outermost shell has seven electrons: one less than that required to fill the shell completely.
Elements!:)
There are many different examples one might reference when it comes to elements of art. For example, the two elements of art for a sculptor would be space and form.
no they are not
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
Sodium losses its electron to chlorine
They were not, as they were often moody and unpredictable.
Elements in group 17 need one electron to gain a stable electron configuration. Two atoms of the same element or two elements in this family forms compounds with a single covalent bond. Examples are chlorine, bromine or iodine chloride.
Group 17 elements are non metals. Any element in group 17 are ready to obtain its stable electron configuration by sharing an electron with another non metal for a bond. Two examples are gaseous chlorine and iodine fluoride.
The halogens are is group VII (17), and thus they all have 7 valence electrons. These will be located in different energy levels for the different halogens, but since they are all also p-block elements, they will all have ns^2 np^5 electron configurations, where n is the period number. Examples: Cl will be [Ne] 3s^2 3p^5 and Br will be [Ar] [Ar] 4s2 3d10 4p5 (note the inclusion of the d-block electrons for Br).

Indium bond with lots of elements to form compounds. Examples: Indium + Phosphorus --> Indium Phosphide Indium + Bromine --> Indium (I/III) Bromide Indium + Fluorine --> Indium Fluoride Indium + Oxygen --> Indium Oxide Indium + Antimony --> Indium Antimonide Indium + Arsenic --> Indium Arsenide

There are many different known battery pack configurations. Some examples of a batter pack configuration include B format, C format, cluster, nested and SBP.
