What else can I help you with?
What elements have 2 protons in the nucleus?
Helium, number two on the periodic table of elements. Nothing else has two protons, for to remove a proton or add a proton is to change the element.
What has a second ionization energy level of 1577?
The element that has the highest second ionization energy is Li. When you remove the first electron from Li you are down to the 1s orbital. They are harder to remove because they are closest to the nucleus.
Why it is so much easier to remove an elcetron from an atom of large atomic weight thabn it is to remove proton?
electrons orbit the nucleus so they come "loose" easier than the protons, which are held in place by a thing called "strong force". strong force is greater than the force holding an electron in orbit around the nucleus.
Why the 1st ionization energy of Na is greter than mg?
Because Be contains more protons and thus has greater nuclear positivity which exerts a stronger attraction for its electrons which requires more energy to remove one of the electrons leading to a higher ionization potential.
What general statement can summarize the trend in the ionization energy when moving across a period of element?
The ionization energy generally increases across a period from left to right. This is because as you move across a period, the effective nuclear charge increases, making it more difficult to remove an electron. Additionally, the increasing number of protons in the nucleus leads to stronger attraction between the nucleus and the electrons.
What elements have 2 protons in the nucleus?
Helium, number two on the periodic table of elements. Nothing else has two protons, for to remove a proton or add a proton is to change the element.
Why is first ionization energy of boron greater than lithium?
The first ionization energy of boron is greater than that of lithium because boron has one more proton in its nucleus than lithium, leading to a stronger attraction between the nucleus and the outer electron being removed. Additionally, boron has a smaller atomic radius than lithium, resulting in stronger electron-electron repulsions for boron, making it harder to remove an electron.
What happens when you add or remove protons in an atom?
Adding or removing protons in an atom changes the element itself, as the number of protons determines the atomic number. Adding a proton creates a new element, while removing a proton changes the atom into a different element. This process also affects the overall charge of the atom, as the number of protons affects the balance of positive charges in the nucleus.
What has a second ionization energy level of 1577?
The element that has the highest second ionization energy is Li. When you remove the first electron from Li you are down to the 1s orbital. They are harder to remove because they are closest to the nucleus.
Why does potassium have a higher first ionization energy than lithium?
Potassium has a higher first ionization energy than lithium because potassium has one more electron shell than lithium, making it harder to remove an electron from the outer shell. As electrons are added further away from the nucleus, the attractive force of the nucleus on the electrons decreases, requiring more energy to remove an electron from the outermost shell in potassium compared to lithium.
What happens when you take away a proton?
When you remove a proton from an atom, it changes into a different element. The element becomes one with an atomic number one less than before, which affects its chemical properties. This process alters the balance of positive and negative charges within the nucleus, potentially leading to radioactive decay in certain situations.
Why is the ionization energy of beryllium is higher than lithium?
Ionization energy represents the energy required to remove electrons from an atom. The first and second ionization energies are relatively small because the lectrons must be removed from the 2s orbital. For the third ionization energy the electron must be removed from the 1s orbital which has less energy than the 2s, and so requires much more energy to be removed.
What happens to the charges of an atom if the one proton and electron are removed?
Removal would cause the atom to change from an atom would change it into an atom of the element with an atomic number one less. Now what happens next? It depends on whether the isotope of the element you have just made is stable. If not it will undergo radioactive decay. (Note hydrogen would of course disappear if you removed 1 proton and 1 electron)
Why are Ionization potential decreases Lithium to Cesium?
The ionization potential decreases from lithium to cesium because the atomic size increases, leading to a greater distance between the outermost electron and the nucleus. This increased distance results in weaker attraction between the electron and the nucleus, making it easier to remove the outermost electron and therefore requiring less energy.
Which atom lithium or cesium needs more energy to become an ion?
Cesium needs more energy to become an ion than lithium because cesium has a higher ionization energy due to its larger atomic size and greater distance of valence electrons from the nucleus. This makes it more difficult to remove electrons from cesium compared to lithium.
How do you charge an atom?
remove either a proton or electron OR add a proton or electron...
What are two reasons why carbon has a higher first ionization energy than lithium?
Ioniz. energy is the amount of energy it takes to remove one electron from an atom. Lithium has one too many electrons before it reaches the highly stable octet of the immediately previous noble gas- so it gives it up really easily. Carbon is farther away from the octet in this manner, so it will take more energy. Also, lithium is a metal and metals tend to lose electrons. Carbon, a nonmetal, tends to gain electrons.
