# What is an element with 4 shells?

## What is an element with 4 shells?

Electrons

Atomic Number Element Energy Levels or “shells”
4 Beryllium (Be) 2
5 Boron (B) 3
6 Carbon (C) 4
7 Nitrogen (N) 5

Can there be 4 electron shells?

This model breaks down at the n=3 shell because each shell has subshells. There are 4 subshells, s, p, d, and f. Each subshell can hold a different number of electrons….Search form.

Shell Subshell Total Number of Electrons in Shell
3rd Shell 3s, 3p, 3d 2 + 6 + 10 = 18
4th Shell 4s, 4p, 4d, 4f 2 + 6 + 10 + 14 = 32

Which period has 4 electron shells?

The p-block elements of period 4 have their valence shell composed of 4s and 4p subshells of the fourth (n = 4) shell and obey the octet rule.

### What elements has 4 valence electrons?

Carbon and silicon BOTH come from Group 14 of the Periodic Table , i.e. both formally have the same number of valence electrons, 4 such electrons………

How many electrons are in the 4th shell?

BRIAN M. The fourth energy level has 18 electrons. The fourth energy level of the periodic table includes the 4s 3d and 4p orbitals.

What element has 4 protons 4 electrons and 6 neutrons?

Beryllium
Atomic Number

Name Protons Neutrons
Lithium 3 4
Beryllium 4 5

#### How many electrons can the 4th shell hold GCSE?

This shell can contain a maximum of two electrons. 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. Then the fourth shell begins to fill….Electron shells.

Energy shell Maximum number of electrons
Second 8
Third 8

What element has 4 electron shells and 3 valence electrons?

Scandium atomic number 21 is in the fourth period. s, p and d . 1st , 2st , 3rd and 4th . for a total of 3 valance electrons.

How many electron shells does Row 4 have?

For the fourth period/row, all of these electrons build the third shell to a maximum of 18 electrons. Remember that the first eight were placed during our trip through the third period/row. The fourth row of the periodic table has transition metals ranging from scandium (21) to zinc (30).

## Does beryllium have 4 valence electrons?

The common examples of such elements are hydrogen (stable with only 2 valence electrons), beryllium (stable with only 4 valence electrons) and boron and aluminum (stable with only 6 valence electrons).

Does tin have 4 valence electrons?

Tin is located in the group 14 of the periodic table, which means that it has four electrons in its outermost shell, i.e. four valence electrons.

How many orbitals does the 4th energy level have?

Thus the total number of atomic orbitals in the fourth energy level of an atom is 16.

### How many electrons are in the outer shell of each element?

Every element in the second column (group two) has two electrons in the outer shell. In additional, How many electrons are in each outer shell?, In general, atoms are most stable, least reactive, when their outermost electron shell is full.

Are there any elements with more than 32 electrons?

No known element has more than 32 electrons in any one shell. This is because the subshells are filled according to the Aufbau principle. The first elements to have more than 32 electrons in one shell would belong to the g-block of period 8 of the periodic table.

How many electrons are in a group 7 element?

The Group 7 elements – fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At) – have seven electrons in the outer shell. Group 0 elements – helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn) – have full outer shells.

#### What happens when an atom has four electrons?

If an atom has four electrons in their outer shell , they generally form covalent bonds i.e. such atoms neither lose electrons nor gain electrons , but share electrons .
