It means that it's a material whose outer shell electrons move freely across the surface of the material. Conductors can carry an electric current
It is a falsifiable theory about some scientific aspect. Falsifiable means that it must be possible to devise a test whose outcome can prove the hypothesis is false.
The octet rule cannot be satisfied in molecules whose total number of valence electrons is an odd number.There are also molecules in which an atom has fewer, or more, than an octet of valence electrons.
In chemistry, an alkali is a substance whose molecules either can donate (or "lend") a pair of electrons to another chemical substance or accept one or more protons (H+).An acid is a substance whose molecules can accept (or "borrow") a pair of electrons or donate one or more protons (H+) respectively.The reaction between an acid and an alkali involves the alkali giving, and the alkali receiving, a pair of electrons so that both are "satisfied". It is in this sense that they are opposites.
An organism whose tissues are completely replaced by minerals is a fossil.
The term for an atom whose electrons have the lowest possible energies is "ground state." In this state, electrons are in their lowest energy levels or orbitals, closest to the nucleus. Excited states refer to when electrons are in higher energy levels, further away from the nucleus.
Asia
yes, they are depicted by a red subatomic particle.
Helium
Electrons in the outer shell, also known as valance electrons, determine how an atom will react. To be more precise I should add that there are transition state elements whose reactivity is also influenced by some of the inner electrons as well.
The lowest positive integer whose English name is spelled with an L is "eleven".
The orbital that will result in the most stable configuration, i.e., the one with the highest first ionization energy, in the resulting atom will be filled first.
Oh, dude, that would be helium! It's like the cool kid at the noble gas party with its full octet of electrons, just chillin' in the corner. So, yeah, helium is the first member of the noble gas family with that full octet vibe.
Magnesium atoms have 12 electrons.
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
54
