Since the atom is electrically neutral, the number of electrons must be the same as the number of protons in the atom, which is the definition of atomic number. Therefore, there are 9 electrons.

How many electron are in a carbon atom?
An electrically neutral carbon atom has the same number of electrons as it does protons: 6, which is equal to its atomic number.
What is an example of an electrically neutral atom?
An electrically neutral atom is one that has an equal number of protons and electrons.
What substance has the same number of protons and electrons?
All neutral atoms have the same number of protons and electrons as they are electrically neutral.
How many electrons are in a neutral atom atomic number 6?
In a neutral atom, the number of electrons is always the same as the atomic number.
If the atomic number of an Atom is 11 how many electrons does Atom have?
You cannot know for sure withoutmore information. An electrically neutral sodium atom (sodium has at. no. 11) will have the same number of electrons as protons; atomic number tells you the number of protons, so this atom has 11 protons and would have 11 electrons if electrically neutral, however, if the atom is charged, it could have more or fewer electrons. Sodium atoms in stars are highly ionized and may have just a few if any any electrons.
How do you calculate number of electrons of a given element?
You can only be sure of the number of electrons if the element is electrically neutral. If an element is electrically neutral, then the number of electrons is the same as the number of protons which is the atomic number of the element. For instance an electrically neutral atom of carbon, there are 6 electrons because there are 6 protons in a carbon atom.
In electrically neutral atoms the number of protons is the same as the number of .?
atomic number = number of protons = number of electrons (in a neutral atom)
An electrically neutral atom of oxygen is likely to have this number of electrons?
Eight, the atomic number of oxygen.
What do you notice about the atomic number and the total number of electrons in an atom of that element?
The atomic number tells you the number of protons that an element has. An electrically neutral atom necessarily has the same number of electrons as it has protons.
Which best describes the relationship between subatomic particles in any neutral atom?
Protons are electrically positive charged, electrons are electrically negative charged, neutrons are electrically neutral. The number of electrons and protons is equal in a neutral atom. Protons and neutrons are in the atomic nucleus, electrons on electron shells, forming electron clouds.
How many electron are in a carbon atom?
An electrically neutral carbon atom has the same number of electrons as it does protons: 6, which is equal to its atomic number.
How many total electrons are present if the atom is electrically neutral in chlorine?
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
What is an example of an electrically neutral atom?
An electrically neutral atom is one that has an equal number of protons and electrons.
The difference between an electrically neutral atom and an ion is that?
The difference is in the number of electrons they have. In a neutral atom, the number of electrons is the same as the number of protons (or atomic number) for that element. In an ion, this is not the case, with either less electrons (an overall positive charge) or more electrons (an overall negative charge) than he neutral atom
How many electrons are in atomic mass of 19?
Fluorine is the element with atomic weight closest to 19 amu. Fluorine has an atomic number of 9, so an electrically neutral fluorine atom would have 9 electrons.
How many electrons does the atom Lr have?
Lawrencium's atomic number is 103. That means it has 103 protons. In order to be electrically neutral then, it must also have 103 electrons.
How many are there electrons in Chlorine?
Chlorine has 17 electrons. The number of electrons in an electrically neutral atom is equal to its atomic number (the number of protons in the nucleus of the atom). The electronic configuration of chlorine is [Ne] 3s2 3p5.
