The atomic number of 17 is the number of protons in nucleus of the atoms of this element (chlorine, Cl). In a neutral atom, the numbers of protons and electrons are equal, so this atom also has 17 electrons. The mass number in this problem is a distractor, and does not contribute to solving the problem. You can use electron configuration to figure out how many electrons are in the second energy level:
1s22s22p63s23p5. You can see that there are 8 electrons in the second energy level in the 2s and 2p orbitals.
You also can look Cl up on the Periodic Table and see that it is in the 3rd period, which means that its second energy level is full (meaning 8 electrons). The last element to add to the second energy level is the noble gas neon (Ne) in the 2nd period. Neon's 2nd energy level is completely filled. So the next element, sodium (Na), starts adding electrons to the 3rd energy level, and its the first element in the 3rd period. All of the rest of the 3rd period elements continue adding electrons to the 3rd energy level s and p orbitals, until the noble gas Argon (Ar), which fills the 3rd energy level s and p orbitals.

How many electrons in atom with atomic number of 9 and atomic mass of 19 and is electrically neutral?
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.
When the number of electrons and protons in a sample of matter are equal the matter is?
neutral. Positive and negative charges cancel each others.
How many protons and electrons are in Aluminum3?
Aluminum's, or Al's, atomic number is 13. Therefore, an electrically neutral aluminum atom would have 13 protons and 13 electrons. However, Al3+ has 3 less electrons than neutral aluminum, an thus only has 10 electrons.
How many protonsnutrons and electrons are in lithuim?
Lithium's atomic number is 3. Thus, it has 3 protons in each atom, all of which have a +1 charge. To be electrically neutral then, lithium must also have 3 electrons per atom.
How many electrons in atom with atomic number of 9 and atomic mass of 19 and is electrically neutral?
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 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.
An electrically neutral atom of oxygen is likely to have this number of electrons?
Eight, the atomic number of oxygen.
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.
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)
How many s electrons does P (atomic number 15) possess?
Phosphorus (neutral atom) has 15 electrons.
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 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 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.
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 atomic particle that has no charge or is electrically neutral?
a neutron
