What else can I help you with?
Which atoms are most reactive?
The most reactive elements have either 1 valence electron or 7 valence electrons
How are particles in a piece of metal held together?
Metals are held together by metallic bonds. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together. Metals are made up of closely packed cations rather than neutral atoms. The valence electrons of metal atoms can be modeled as a sea of electrons. The valence electrons are mobile and can drift freely from one part of the metal to another. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together.
Metal with 25 electrons?
In a stable, Neutral system, the protons and electrons will be equal. The element with atomic number 25 is Manganese (Mn), See the periodic table
Why does metal conduct electricity?
metal conducts electricity because it allows electrons to move freely as well as it has free electrons, unlike insulators(non-metals) which do not have free electrons. When the electrons are allowed to move freely in a substance, it is a good conductor and allows electric charge to flow.
Distinguish between a metal and a metal - containing compound?
Only one of these occurs naturally.
What metal has two valence electrons?
Calcium is a metal that has two valence electrons.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
How many valence electrons are in zirconium atom?
protons:40electron:40neutrons: can vary, however, the main isotope has 80
What is the total number of valence electrons in an atom with the total of thirteen protons?
13 protons would indicate the element is aluminum, Al. It has the electron configuration of1s2 2s2 2p6 3s2 3p1. In the 3rd energy level, there are 3 electrons, thus it has a total of 3 valence electrons.
What alkaline earth metal has 2 valence electrons?
Beryllium is the alkaline earth metal that has 2 valence electrons.
How many valence electrons does metalloids have?
Metalloids typically have 3 to 6 valence electrons. This intermediate number of valence electrons allows metalloids to exhibit both metal and non-metal characteristics.
What will a non-metal do with its valence electrons?
Nonmetals attract electrons.
What will a metal do with its valence electrons Why?
they are making metal bonds. that is the purpose.
How many valence electrons are in iridium?
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
How many valence electrons does an metal have?
1
Is a metals luster is due to its valence electrons?
Most of the properties of a metal, including lustre, are due to the metallic bonding of the electrons.
