What else can I help you with?
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Why do valence electrons determine how an atom interacts with other atom?
They are on the outside of the atom. (Apex 2021)
Does an electron determine what element it is?
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
What is key in determining whether an atom will form a bond with another atom?
Valence electrons
Why does an atom with only one electron in its valence shell make a better conductor than an atom with seven electrons in its valence shell?
An atom with only one electron in its valence shell is more likely to lose that electron easily, making it a better conductor. In contrast, an atom with seven electrons in its valence shell is more stable and less likely to lose electrons, thus making it a poor conductor.
Does the intensity of light determine whether radiation will eject electrons?
No. The wavelength of the light determines whether an electron will be ejected from an atom.
Why you prefer silicon atom as comp conductor atom?
the silicon is the insulator
What is a solid in which electrons are able to move about easily from atom to atom?
A conductor
What allows a conductor to conduct electricity?
Conductors are substances where electrons can freely move from atom to atom.
Does the number of electrons in the innermost shell of an atom determine whether the atom has high or low reactivity?
Only in hydrogen or helium, because in these two elements only the innermost shell is also the outermost shell.
How do you determine whether the equation is balanced?
To determine if an equation is balanced, compare the number of each type of atom on the reactant side to the product side. Make sure there is an equal number of each type of atom on both sides of the equation. If the number of atoms is balanced, the equation is balanced.
What are the criteria for the formation of cations?
A cation is formed when an atom loss electrons.
What is a solid in which electrons are able to move about easily from atom to another?
A conductor
Why do valence electrons determine how an atom interacts with other atom?
They are on the outside of the atom. (Apex 2021)
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
If an atom has four valence electrons is it an anion?
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
Does an electron determine what element it is?
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
