What does conductor mean in science?
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
What does scientific hypothesis mean?
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.
Which three elements violate the octet rule?
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.
What is the chemical opposite of acid?
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.
What is the answer to this describes a organism whose tissues are completely replaced by minerals?
An organism whose tissues are completely replaced by minerals is a fossil.
What is the term for an atom whose electrons have the lowest possible energies?
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.
Whose continent has the lowest land feature?
Asia
Did niels bohr's atom model have a cloud of positive charge?
yes, they are depicted by a red subatomic particle.
What element whose valence electrons is full with two electrons on the periodic table?
Helium
Do electrons in the lowest energy level of an atom that determine how that atom reacts?
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.
What is the lowest number with the letter L in it?
The lowest positive integer whose English name is spelled with an L is "eleven".
Whose rule or principle delineates the placement of additional electrons in the unfilled orbital of lowest energy?
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.
Who was the first member of the noble gas family whose highest energy level consists of an octet of electrons is?
Helium is the first member of the noble gas family whose highest energy level consists of an octet of electrons.
A substance that contains the element whose atoms have 12 electrons indicate which element?
Magnesium atoms have 12 electrons.
How many electrons are present in an atom of mercury whose atomic number is 80 and whose mass is 201?
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
How many electrons would be found in the ion whose symbol is you -i?
54
How many electrons are present in an atom of mercury whose mass atomic number is 80 and whose mass number is 201?
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
