What else can I help you with?
In what way do these atoms corresponds and in what way do they differin terms of their mass numbers?
Atoms correspond in that they are all made up of protons, neutrons, and electrons. However, they differ in their mass numbers, which is the sum of protons and neutrons. Atoms of different elements have different mass numbers due to varying numbers of protons and neutrons.
What is true of an atoms nucleus?
It contains Protons and Neutron's.
Do electrons move easily?
Yes, electrons move easily through conductive materials like metals due to their negative charge and low mass. In insulating materials, electrons are tightly bound to atoms and do not move easily.
How doe ions differ from atoms?
No. Ions are formed by the loss or gain of electrons. the mass of electrons is negligible when compared to the mass of the nucleus (or the atom). Hence ions have the same mass as that of the atom of the element.
Why do protons and electrons aproximately equal a atomic mass?
Protons are much heavier (1800 X approx) than electrons! Atomic mass is due to the mass of the protons and neutrons only a very small % of atomic mass is due to electrons.
What are charged atoms due to a loss or gain of electrons?
all charged particles are ions. cations are positive meaning they have more protons than electrons. anions are negative meaning they have more electrons than protons
Most of the volume of an atom is taken it up by the and most of the mass of an atom is found in the?
Most of the volume of an atom is taken up by the electron cloud, which surrounds the nucleus and is formed by the movement of electrons. In contrast, most of the mass of an atom is found in the nucleus, which contains protons and neutrons. This concentration of mass in the nucleus is due to the significantly greater mass of these subatomic particles compared to electrons.
What bond is most likely to form between 2 gold atoms?
A metallic bond is most likely to form between two gold atoms due to the nature of gold being a metal. Metallic bonds are formed by the sharing of electrons between metal atoms, allowing for the free movement of electrons and high electrical conductivity.
Does an insulator allow the flow of electrons?
Yes . Some insulators do allow the flow of electrons but most do not.
Which of daltons 4 ideas were proven incorrect?
Dalton's idea that atoms are indivisible particles has been proven incorrect, as atoms are made up of protons, neutrons, and electrons. Additionally, his idea that all atoms of the same element are identical in mass has been disproven due to the existence of isotopes.
Atoms that have an electrical charge due to a gain or loss of electrons are called what?
Ions. Cations have lost electrons and have a positive charge. Anions have gained electrons and have a negative charge.
Why the mass of hydrogen molecule is greater then the mass of hydrogen atom?
The mass of a hydrogen molecule is greater than that of a single hydrogen atom because a hydrogen molecule consists of two hydrogen atoms bonded together. When two hydrogen atoms bond to form a molecule, they share electrons, resulting in a decrease in the individual mass of each atom. However, the total mass of the molecule is slightly higher due to the binding energy that holds the atoms together.
