What do you notice about the number of enery level or shells as you move down a group or column in the periodic table?
Down a group, the number of energy levels (or shells) increases.
What is the number of energy shells in a zinc atom?
There are four energy shells. The levels go: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10. This is because there are 30 electrons.
Why sulfur has a lower ionisation energy than phosphorus?
because it has many number of shells.
What do all elements in the same period on the period the periodic table have in common?
A. They have the same number of protons.B. They have the same number of orbitals.C. They have the same number of electrons.D. They have the same number of neutrons.
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
What do you notice about the number of enery level or shells as you move down a group or column in the periodic table?
Down a group, the number of energy levels (or shells) increases.
What Elements in the same row are filling up the same energy level as you move from left to right?
They have the same number of shells (or energy levels).
How many energy shells does silver have?
Lead has six energy levels. It has an atomic number of 82 which is also equivalent to the number of protons and electrons.
What is the number of energy shells in magnesium?
2 8 2
What is the number of energy levels of fermium?
Fermium has seven electron shells.
What is the number of energy shells in a zinc atom?
There are four energy shells. The levels go: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10. This is because there are 30 electrons.
How many electron shells does lead have?
Six shells. Check http://en.wikipedia.org/wiki/Lead
Number of energy level in sulfur?
Sulfur has 16 electrons in three shells, 2, 8, and 6 in the first, second and third shells
Why sulfur has a lower ionisation energy than phosphorus?
because it has many number of shells.
What happens to to the number of energy levels or shells as you move from left to right across rows or periods in the period table?
As you go down the horizontal rows, the energy levels increase.
Does the number of occupied energy levels change when you go down the groups?
Yes, the occupied energy level changes. The number of shells increases down the group.
What is sodium's number of electron shells?
Sodium has 3 energy levels, 1s, 2s, 2p, and 3s.
