The molar mass of 13-carbon is approximately 13g. Hence 9g contains 0.6923 moles.
Fluorine has 9 electrons.
That seems to be an invalid notation. The subscript refers to the number of protons (5=Boron), but 'C' refers to the element (Carbon). Ignoring the 'C', Protons: 5 (Boron) Neutrons: 13-5= 8 Neutrons Electrons: 4+5= 9 Electrons
There are 9 total electrons in an atom of Fluorine.
The CN- ion has 10 valence electrons. The carbon atom contributes 4 valence electrons, and the nitrogen atom contributes 5 valence electrons. Additionally, the negative charge adds 1 electron, resulting in a total of 10 valence electrons.
The element with the electron configuration He2s2 2p5 is fluorine. The atomic number of fluorine is 9, which means it has 9 electrons. The electron configuration represents 2 electrons in the 2s orbital and 5 electrons in the 2p orbital, giving a total of 7 valence electrons.

A molecule of crotononitrile (C4H5N) has 9 valence electrons. This is calculated by adding the valence electrons of each element: carbon (4), hydrogen (5), and nitrogen (1).
A fluorine atom has 9 electrons.
There are 9 total electrons in an atom of Fluorine.
Atoms of elements have a fixed number of electrons that can bond with other atoms. Carbon has 4 electrons that can bond with other atoms. So 4 hydrogen atoms can bond with one carbon atom.
The CN- ion has 10 valence electrons. The carbon atom contributes 4 valence electrons, and the nitrogen atom contributes 5 valence electrons. Additionally, the negative charge adds 1 electron, resulting in a total of 10 valence electrons.
In the Lewis structure of CHI₃ (iodoform), the central carbon atom is bonded to one hydrogen atom and three iodine atoms. The carbon atom has no unbonded electrons, while each iodine atom has three unbonded pairs of electrons. Therefore, there are a total of 9 unbonded electrons from the three iodine atoms in CHI₃.
9
In a fluorine atom: 9 protons, 10 neutrons, and 9 electrons.
The element with the electron configuration He2s2 2p5 is fluorine. The atomic number of fluorine is 9, which means it has 9 electrons. The electron configuration represents 2 electrons in the 2s orbital and 5 electrons in the 2p orbital, giving a total of 7 valence electrons.
The atomic number of an element tells you how many electrons there are and how many protons there are.
