Does shell 3 have 8 or 18 electrons?

In this sense the third shell can hold 8 electrons. 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. … So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.

Does every shell have 8 electrons?

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. … For an explanation of why electrons exist in these shells see electron configuration.

What is the 4th energy level?

The fourth energy level has 18 electrons. The fourth energy level of the periodic table includes the 4s 3d and 4p orbitals. The 4p orbital holds 6 electrons. There is a 4d orbital with 10 electrons which coincides with the 5th energy level of the periodic table.

Why is the third shell 8 or 18?

The third shell of an atom has 18 electrons only not 8 electrons. You might be confused because first the electrons of 4s are filled and then the 10 electrons of 3d shells are filled. They are filled because of the n-l rule. Hence, you might be confused that the 3rd shell has only 8 electrons only….

Does M shell have 8 or 18 electrons?

energy levels or K,L,M, N… … K-shell is the first energy level and can have a maximum of 2 electrons. L-shell is the second energy level and can have a maximum of 8 electrons. M-shell is the third energy level and can have a maximum of 8 electrons.

Why do we put 8 electrons in M shell?

The maximum capacity of a shell to hold electrons is 8. The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule called the Octet rule.

What is the 2 8 8 electron rule?

Transition metals are able to put more than eight electrons in the shell that is one in from the outermost shell. Think about argon (Ar). It has 18 electrons set up in a 2-8-8 order. Scandium (Sc) is only 3 spots away with 21 electrons, but it has a configuration of 2-8-9-2.

How many electrons are there in 3rd shell?

The second shell can hold a maximum of eight electrons. When this is filled, electrons go into the third shell, which also holds a maximum of eight electrons.

How many electrons are in the 3rd shell?

18 electrons
Any orbital can hold a maximum of 2 electrons with opposite spin. The first shell has one 1s orbital and holds 2 electrons. The second shell holds 8 electrons; 2 in a 2s orbital and 6 in three 2p orbitals. The third shell holds 18 electrons; 2 in a 3s orbital; 6 in three 3p orbitals; and 10 in five 3d orbitals.

What is the element with 8 electrons?

Oxygen
Oxygen is the eighth element in the periodic table, with the symbol O. This means that it has eight electrons in its neutral state.

How do electrons fill in Shell?

Electrons fill orbitals starting at the lowest available energy state before filling higher states. Aufbau procedure: Determine number of electrons for the atom of interest. Fill available orbitals starting with the lowest-energy levels first and avoid pairing electrons in a single orbital until it is necessary.

Why is gold Au in the periodic table?

Gold symbol on the periodic table is Au that was used because of its Latin name aurum. It is an expensive metal, with a high boiling point, that is used as money and/ or jewelry.

Who is known as the father of the periodic table?

Dmitri Mendeleev, Russian in full Dmitry Ivanovich Mendeleyev, (born January 27 (February 8, New Style), 1834, Tobolsk, Siberia, Russian Empire—died January 20 (February 2), 1907, St. Petersburg, Russia), Russian chemist who developed the periodic classification of the elements.

Can gold be made?

Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements. … Gold is the chemical element with 79 protons in each atomic nucleus.

Is Diamond a metal?

Diamond is not considered as a non-metal in the exceptional category as diamond is a form of carbon. It is not classified as an element. … It is an allotrope of carbon.

Is gold Magnetic?

Gold had long been considered a non-magnetic metal. But researchers recently discovered that gold can in fact be magnetized by applying heat. Gold had long been considered a non-magnetic metal. But researchers at Tohoku University recently discovered that gold can in fact be magnetized by applying heat.

Can you make platinum?

Extracting platinum is both capital and labour intensive. It can take up to 6 months and 7 to 12 tons of ore to produce one troy ounce (31.135g) of pure platinum. The first step in this process is to crush platinum containing ore and immerse it in reagent containing water — a process known as ‘froth flotation’.

How can you turn lead into gold?
