Which element has the highest effective nuclear charge?
sodium cationThe sodium cation has the largest effective nuclear charge, which results in electrons being held the tightest, and therefore Na+ has the smallest atomic radius. “valence shell.”
Which element or elements have the largest effective nuclear charge?
Because chlorine is in the same period as phosphorus and sodium, but has the most protons in its shell (the most right within the same period) it has the greatest effective nuclear charge.
Which element has the smallest effective nuclear charge?
Among elements 1-18, H has the smallest effective nuclear charge if we use the equation Zeff = Z – S to calculate Zeff.
What is a Zeff?
Zeff is a measure of how strongly any given electron is actually held in place within an atom, and it varies from one electron to another within an atom. … It’s the effective nuclear charge that an electron feels due to other electrons shielding it some of the charge from the nucleus.
What element has a nuclear charge of 47?

What is 48 on the periodic table?
CadmiumCadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury.
What is poor shielding effect?
Poor shielding means poor screening of nuclear charge. In other words, the nuclear charge is not effectively screened by electrons in question. The shielding effect of different orbitals is as follows: s orbital’s > p orbital’s> d orbital’s> f orbital’s.
Why is Zeff important?
The effective nuclear charge is due to the presence of protons in the nucleus of an atom. It can tell us about many properties of an element. If an atom has more effective nuclear charge then it can attract the electrons more and therefore the atomic size will decrease.
Is nuclear charge positive or negative?
The effective nuclear charge (often symbolized as Zeff or Z*) is the net positive charge experienced by an electron in a multi-electron atom. The term “effective” is used because the shielding effect of negatively charged electrons prevents higher orbital electrons from experiencing the full nuclear charge.
What do you call the element from atomic number 57 71?
The series of elements are called the lanthanides because they’re so similar to the element lanthanum. The general symbol Ln is used when referring to the lanthanides. … The lanthanide elements range in atomic number from 57 to 71.
What is the nuclear charge of an element?
Effective nuclear charge – the attractive positive charge of nuclear protons acting on valence electrons. The effective nuclear charge is always less than the total number of protons present in a nucleus due to shielding effect. Effective nuclear charge is behind all other periodic table tendencies.
Why is cadmium bad for you?
Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body’s cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.
