How many shells in 20 electrons?
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.
How many shells are there in selenium atom?
A selenium atom typically contains 34 electrons distributed in different shells around the nucleus. The electrons are arranged in energy levels or shells, with the first shell holding a maximum of 2 electrons, the second shell holding up to 8 electrons, the third shell holding up to 18 electrons, and the fourth shell holding up to 6 electrons for selenium.
How many electron shells would at atom have if it had 16 electrons?
An atom with 16 electrons would have 3 electron shells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 8 electrons.
How many shell do 2 electrons need?
Only one. The first shell can have up to 2 electrons.
You have two completely filled shells and no electrons anywhere else?
IF you have 2 complete full shells and no electrons any were else that means you have 2 electrons in the first shell and 8 electrons in the second shell which is 10 electrons in other words it is neon
16 electrons need how many shells?
16 electrons would fill up the first four shells in an atom: 2 electrons in the first shell, 8 electrons in the second shell, 4 electrons in the third shell, and 2 electrons in the fourth shell.
How many shells in 20 electrons?
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.
How many electrons are needed to fill the first three electron shells?
The first electron shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 18 electrons. Therefore, a total of 28 electrons are needed to fill the first three electron shells.
How many shells in sodium?
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 :)
An atom with 10 electrons must have how many shells?
An atom with 10 electrons will have 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons.
How many outer shell are in calcium?
The outer shell of calcium has two electrons.
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
How many shells does 10 electrons need?
10 electrons would need 2 shells to accommodate them. The first shell can hold up to 2 electrons, while the second shell can hold up to 8 electrons.
Why Two electron shells in oxygen?
Oxygen has two electron shells because it has eight electrons. The first shell can hold a maximum of two electrons, while the second shell can hold up to eight electrons. In oxygen, two electrons occupy the first shell and the remaining six electrons occupy the second shell to satisfy the octet rule.
How many electron shells does Argon have?
3 shells; 2 electrons in the first shell, 8 in the second shell and 8 in the third shell.
How many shells are there in selenium atom?
A selenium atom typically contains 34 electrons distributed in different shells around the nucleus. The electrons are arranged in energy levels or shells, with the first shell holding a maximum of 2 electrons, the second shell holding up to 8 electrons, the third shell holding up to 18 electrons, and the fourth shell holding up to 6 electrons for selenium.
What is the atomic structure for oxygen and phosphate?
Oxygen has 8 protons, 8 neutrons, and 8 electrons. Phosphate has 15 protons, 16 neutrons, and 15 electrons. Oxygen has 2 electron shells, with 2 electrons in the first shell and 6 electrons in the second shell. Phosphate has 3 electron shells, with 2 electrons in the first shell, 8 electrons in the second shell, and 5 electrons in the third shell.
