What are anions of a particular element generally larger than the atoms of the same element?
Its C. Anions gain electrons without gaining protons. This increased negative charge with no increase in positive charge allows electrons to orbit farther from the nucleus; therefore the ions are larger.
Anions of a particular element are generally larger than the atoms of the same element what best explains this difference?
its c. anions gain electrons without gaining protons. this increased negetive charge with no increase in positive chare allows electrons to orbit farther from the nuculeus; therefore the ions are larger.
What is true of all atoms that are anions A more electrons than protons B more protons than electrons C fewer protons than neutral atom of same element D more neutrons than protons E net charge is 1-?
Answer A is correct: there are more electrons than protons. However, if a particle is an anion, it is not an atom. Atoms are electrically neutral.
Which of the following are always larger than the neutral atoms from which they are formed.. A. positive ions B. negative ions C. cations D. none of the above?
B. Negative ions. ( anions ) They have taken electron(s) into their valance shell and have increased their size this way.
Largest element in a row and largest element in a column?
The largest element in a Period (row) will be on the right of that Period (i.e. an inert gas). The largest element in a Group (column) will be at the bottom of that group. Examples; Helium is larger than Hydrogen (Period 1) Krypton is larger than Potassium (Period 3) Francium is larger than Lithium (Group 1) Ununquadium is larger than Carbon (Group 3)
What are anions of a particular element generally larger than the atoms of the same element?
Its C. Anions gain electrons without gaining protons. This increased negative charge with no increase in positive charge allows electrons to orbit farther from the nucleus; therefore the ions are larger.
Is a cation larger or smaller than a neutral element?
Cation is always smaller than corresponding neutral atom.

Is iodine a cation?
Iodine itself is an element, not an ion. It forms anions rather than cations.
Which is larger a atom or a element explain?
an atom is larger than an element

What is the relationship between the radius of a anion and that of the atom from which it is formed?
Anions are much larger than their corresponding parent.
Why is an anion larger than its parent atom?
The size of an anion is larger than its parent atom because anions are formed due to the gain of electrons. When the electrons increase, there are still the same number of protons. The attractive force is thus reduced as there are the same number of protons attracting an increased number of electrons. This causes the electrons to not be bound as tightly to the nucleus resulting in an increase in size. In other words, anions have one or more extra electrons that contribute to the size of the atom. These extra electrons increase its size and make it larger than the neutral atom.
O2- is larger than O?
Yes, because anions are always bigger than the atom in its ground state. Cations are smaller
What has a larger radius a bromine atom or a bromine ion?
That depends: is it a positive ion (Br+) or a negative ion (Br-)? An ion with a charge of +1 has one less electron than the element would have normally. An ion with a charge of -1 has one more electron than normal. It seems kind of strange that -1 means one more, and +1 means one less, but that's because an electron has a charge of -1, so if there is one less electron than is needed to keep the atomic charge balanced, the charge will be positive by 1. Cations (pronounced cat-ions, not cashons), ions with a positive charge and therefore fewer electrons than the neutral atom, have a smaller atomic radius than the neutral atom. Anions, ions with a negative charge and therefore more electrons than usual, have a larger atomic radius than the neutral atom. So a bromine cation would have a smaller radius, and a bromine anion would have a larger atomic radius. NOTE: when referring to a neutral atom, the atom is of THE SAME ELEMENT as the ion. Otherwise, the comparison is not necessarily true.
Which is larger (a) a cation or the neutral atom from which it forms?
The neutral metal atom is larger than its cation, because to form a cation, the valence energy level of electrons is lost, reducing its radius.
Why is a bromide ion larger than a bromine atom?
Bromide ions are larger than bromine atoms because the ion has one more electron than the neutral atom. The extra electron is less tightly bound than the other electrons because it experiences a smaller effective nuclear charge. Other anions are also larger than their corresponding atoms for the same reason; cations, on the other hand, are smaller than their corresponding atoms because they have fewer electrons.
