Modern 16ga shells are 2 3/4". Older shells were usually 2 1/2" or maybe 2 9/16". You can buy 2 1/2" 16ga shells from Polywad and also RST I believe.

Period number = no. of electron shells. Therefore neon has two shells.

Neon mate, has 2 shells. there are 2 in the firstand 8 in the second as there are 10 ions altogether.

Polonium has 6 electron shells.

if an element has 1 shell in its atom it is in period 1and so on...

2 shells=period 2

3 shells=period 3

4 shells=period 4

5 shells=period 5

6 shells=period 6

7 shells=period 7

No, not all alkaline metals have 2 electron shells. Alkaline metals like lithium, sodium, and potassium have 2 electron shells, but alkaline earth metals like magnesium and calcium have 3 electron shells.

2 3/4" or 3" shells

Yes, you can.

The number of electron shells in a normal Lithium atom is 2.

It has an electron configuration of 1s22s1

no

No. will handle 2 9/16 old shells or 2 3/34 modern regular pressure shells.

No, lithium has 2 electron shells (1s2 2s1) and oxygen has 2 electron shells (1s2 2s2 2p4).

Radium has seven electron shells; the valence of radium is 2+.

No, magnesium (Mg) has 3 atomic shells while sodium (Na) has 2 atomic shells. The number of atomic shells is determined by the number of electron shells in an atom.

The answer is 24 shells

2 8 2

Yes, However, the reverse is not true- 3 inch shells may NOT be safely fired in a gun chambered for 2 3/4 inch shells.

Yes, However, the reverse is not true- 3 inch shells may NOT be safely fired in a gun chambered for 2 3/4 inch shells.

yes

Rubidium has 5 shells because the first shells has 1 electron, the next 2 shells have 8 electrons, the fourth shells has 18 electrons and the last shells has 2 electrons. the atomic number is 37, 1+8+8+18+2=37. Therefore Rb has 5 shells. :D

Nickel has 3 (three) electron shells.

The atom that has 2 completely filled electron shells and no electrons anywhere else is helium. Helium has a total of 2 electrons, with both shells being completely filled with 2 electrons in the first shell.

Yes. A 3-1/2" chamber will accept 2-3/4" & 3" & 3-1/2 shells

Sulfur has more electron shells than oxygen. Oxygen has 2 electron shells (K and L), while sulfur has 3 electron shells (K, L, and M).

2. There are 2 syllables.

As silicon is in the third row of the periodic table, it has 3 shells. (2-8-4)

First make sure that your shotgun can cycle 2 3/4 inch shells. To do this, read the barrel, if it say 2 9/16 shells then that is your problem. Early 16ga. Browning's were made to cycle 2 9/16 inch shells. Next, check your ring setup inside of your stock, it may not be set properly.

A neutral xenon atom has 8 electron shells with 6 completely filled shells and 2 partially filled shells.

It is called a clam.

i cant answer it

A magnesium atom has 12 electrons arranged in 3 shells. The electron configuration of magnesium is 2-8-2, indicating that it has 2 electrons in the first shell, 8 in the second shell, and 2 in the third shell.

The n = 2 level of hydrogen can hold eight total electrons--6 in the p shells and 2 in the s shells.

The electron configuration of silicon is 2,8,4. or in other words, 3s^2, 3p^2. Therefore, there are three shells around silicon.

The only length I've seen is 2 3/4 in shells. That is the length of the chamber on my Model 77-B in 16 gauge.

Early guns, those made prior to the 1930s may have 2 1/2 inch or 2 5/8 inch chambers, So, while modern 16 gauge shells are 2 3/4", early 16 gauge shells were 2 1/2".

Sodium typically has 11 electrons arranged in 3 shells: 2 in the first shell, 8 in the second shell, and 1 in the third shell.

Fluorine has 2 electron shells. Its electron configuration is 2-7, indicating that it has 2 electrons in the first shell and 7 electrons in the second shell.

There are 4 shells in 20 electrons: 2 electrons in the first shell, 8 in the second, 8 in the third, and 2 in the fourth shell.

Boron has two orbital shells. The first shell contains 2 electrons, while the second shell can hold up to 8 electrons. Boron typically has 5 electrons, with 2 in the first shell and 3 in the second shell.

An iron atom has an electron arrangement of 2-8-14-2 in its four electron shells. This means it has 26 electrons distributed among these shells based on the aufbau principle.

Yes, shorter shells are no problem.

Francium has seven electron shells; electrons per shell: 2, 8, 18, 32, 18, 8, 1.

2 .5 shells

Beryllium

Beryllium has 2 electron shells.

Yes.

Yes you may use the 2 1/2in shells in your .410 gauge shotgun.

Clean the forward end of the chamber after shooting.

Calcium has 4 electron shells. The electron configuration of calcium is 1s2 2s2 2p6 3s2 3p6 4s2.
