How many electrons are present in the outer shell of an atom with an atomic number of 14 and an atomic weight of 29?
Atomic number is the number of protons. In a neutral atom, the number of protons is equal to the number of electrons. So, in your example, the number of electrons in this atom is 14. The first energy shell can take 2 electrons, the second energy shell can take 8 electrons, and the third energy shell can take 18 electrons. If there are 14 total electrons, 10 would be found in the first two energy shells, leaving 4 for the third energy shell.
What is the outer shell number for beryllium?
The outer shell number for beryllium is 2. Beryllium has 4 electrons, so in its electron configuration, 2 electrons are in the first energy level and 2 electrons are in the second energy level, making the outer shell number 2.
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.
Does Helium have 2 electrons in the first shell and 4 in the second?
No, Helium has 2 electrons in total, both of which occupy the first electron shell. The first electron shell can hold a maximum of 2 electrons, so Helium's electron configuration is 2.
Which element has 4 valence electrons in the 6th shell?
The element with 4 valence electrons in the 6th shell is lead (Pb). Lead has 4 electrons in its outermost shell, which is the 6th electron shell.
How many electrons does carbon have in the outer energy level or shell?
In a neutral carbon atom, there will be 4 electrons in the outer most valence shell.

How any electrons does lead have in its outermost energy level?
Lead has 4 electrons in its outermost shell.
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 electrons does carbon have in its first electron shell?
Carbon has two electrons in its inner shell and four in its outer 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 in each ring in a silicon atom?
Silicon is the group 4, period 3 metalloid. It's electron configuration is 1s2 2s2 2p6 3s2 3p2. Thus it has 2 electrons in its first shell, 8 in its second, and 4 in its third.
What is the Electron shell arrangement of a Silicon Atom?

How many electrons on the outer shell of a silicon?
Silicon has 14 electrons. There are four electrons that orbit the nucleus in the outermost, or "valence," energy level, which are given to, accepted from, or shared with other atoms.
