If an element is a gas and does not conduct electricity or heat what possible number of valence electrons does an atom of it have?
An atom that is a gas, does not conduct electricity or heat, likely has 8 valence electrons. This suggests it belongs to the noble gas group in the periodic table, characterized by having full valence shells and being non-reactive.
Do freely moving valence electrons account for electrical conductivity in metals?
Yes, freely moving valence electrons account for electrical conductivity in metals. These electrons are not bound to specific atoms and can move throughout the metal lattice, creating a flow of electric charge when a voltage is applied. This mobility of electrons allows metals to conduct electricity efficiently.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
Pick the statement that is most likely to be true of an element with LOW electronegativity?
An element with low electronegativity is likely to be a good conductor of electricity since it has a weaker ability to attract and hold on to electrons. This means that the element is less likely to form strong covalent bonds with other elements, making it more likely to easily share electrons and conduct electricity.
Why are metals to conduct electricity?
Because their valence electrons are free to move.
What elements are not malleable and do not conduct electricity?
Insulators. Their valence electrons are tightly bound because the valence shell is close to full or full. Since each shell can only only hold a certain amount of electrons, the number of electrons depends on which shell is the outer or valence shell.
The valence electrons found in metals are different from nonmetals because .?
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely

What is having the ability to conduct electricity or heat?
Metals are good conductors of heat and electricity.The metal conduct electricity because they have unbound electrons (or valence electrons) that can conduct the electricity as the electrons can move. Similarly, they conduct heat because the electrons are free to vibrate which causes neighbouring electrons to vibrate and so on along the entire piece of metal. These vibrations cause the metal to conduct the heat.Graphite, a type of carbon, is also a good conductor of electricity. Graphite is soot.
How many valence electrons do transitions elements have?
How many valence electrons do transition elements have?
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).

Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
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.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
