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. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two 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.

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

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

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.

Nickel has 3 (three) electron shells.

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

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

2. There are 2 syllables.

Oxygen is on period 2 whereas sulfur is on period 3. Therefore, sulfur has more electron shells than oxygen.

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

It is called a clam.

i cant answer it

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

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 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 sodium atom has 3 shells where 2 electrons are in the first shell, 8 in the second and 1 in the third shell; which isn't stable..... and its symbol is Na :)

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".

Florine have only 2 shells namely 1s and 2s is is inner and 2s is outer shell I there is any question related to chemistry then ask me....

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.

The electron configuration of iron is [Ar]3d64s2.

The electron shells contain 2, 8, 14 and 2 electrons.

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.

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

Yes.

Beryllium has 2 electron shells.

4 electron shells; 2 electrons in first, 8 in second, 8 in third and 2 in valence shell.

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

Clean the forward end of the chamber after shooting.
