Multiply the element's atomic number by the number of atoms of this type (see Step 1) in the molecule. Repeat for all elements in the molecule, then add up all the products to calculate the number of electrons. In the first example, the number of electrons in KNO3 equals (19 x 1) ...
find the valance orbital of silicon. Silicon is element number 14 so it has 14 electrons. The orbitals available for silicon are 1s, 2s, 2p, 3s and 3p. The electrons fill the 1s, 2s, 2p and 3s orbitals and place the last two electrons in the 3p orbitals...
Which statement best describes the electronegativity of an element? (a) Electronegativity of an atom is its ability to produce energy while losing an electron. (b) Electronegativity of an atom is its ability to attract electrons during bond formation. (c) Based on electronegativity...
Valency is another term referring to the number of valence electrons orbiting the nucleus of an atom. Valence electrons are those found in the outer electron shell. These are the electrons responsible for an element's reactions with other elements....
Ionization Energy:The energy required to remove one electron (the outer-most electron) from an element is referred to as ionization energy. Elements with low ionization energy are more likely to lose one or more electrons to become a positive ion. If an element has high ioni...
An uninterruptible power supply is something you might not think about until you really need it. MF3d / Getty Images It's a foundational element of device integrity, but you wouldn't be the first person to beg the question, "What is a UPS?" In short, a UPS safeguards electronic device...
To determine how many electrons are present in the outermost orbit of helium, we can follow these steps:1. Identify the Element: We are looking at helium (He), which is a chemical element.2. Find the Atomic Numbe
When a metal wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor. The moment contact is made, the free electrons of the conductor are forced to drift toward the positive terminal under the influence of...
To determine the valence electrons in an atom, you write the electron configuration of the element in noble-gas-inner-core form. The electrons outside... Learn more about this topic: Valence Electron | Definition, Configuration & Examples ...
Inside an ionization detector is a small amount (perhaps 1/5000th of a gram) ofamericium-241. Theradioactiveelement americium has a half-life of 432 years, and is a good source ofalpha particles. Another way to talk about the amount of americium in the detector is to say that a typica...
