This is because there are 2 more electrons (18 e-) than protons (16 p+)

Remember that the number of protons is always equal to the atomic number.

Mass number 33 is of no importance for this answer. It is equal to the SUM of protons AND neutrons of this particular isotope (Sulfur-33, or 33S, <1% of all natural sulfur).

How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?

Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.


How many protons electrons and neutrons are there in an atom that has an atomic number of 8 and a mass of 15?

Learn that the atomic number means the number of protons. The mass number is the number of protons and the number of neutrons. So if we take the number of protons from the mass number then we get the number of neutrons that are present (mass umber - atomic number = number of neutrons). in this case 15 - 8 = 7. Since you dont mention there is any charge on the atom ill assume that its charge is neutral. For an atoms charge to be neutral then the positive charges from protons must equal the negative charges from electrons and vica versa. So for this to be the case with 8 protons then we must have 8 electrons.


How do you calculate the number of protons neutrons and electrons of an atom?

The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.


Element whose neutral atoms have 12 electrons?

Atoms of Magnesium have 12 electrons. Elements in the periodic table with a neutral charge must all have a number of electrons equal to the number of protons in the nucleus. Since Magnesium has an atomic number of 12, and the atomic number is also known as the PROTON number, then it must also have 12 electrons to balance out the charge. Magnesium has an atomic mass of about 24 - the other 12 units of mass being made up of neutrons.


When balancing a nuclear equation what two quantities are conserved when balancing a nuclear equation?

In a nuclear equation, the total number of protons and neutrons is conserved. This means that the sum of the mass numbers and the sum of the atomic numbers must be the same on both sides of the equation before and after the reaction.

Why do you calculate the number of electrons by the atomic mass and number?

You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.


How do you get the number of protons electrons and neutrons from the atomic mass number and atomic number?

Number of protons = atomic number Number of neutrons = Atomic Mass (rounded to the nearest whole number) minus the atomic number Number of electrons in a stable element = number of protons Number of electrons in an unstable element = atomic number minus the charge


An ion of iron has an 26 protons 30 neutrons and 23 electrons. What are its atomic number atomic mass and net charge?

Atomic number : 26Atomic mass : 55.845 Net charge : +3


What is the atomic number atomic mass and net charge of an atom of iron?

Atomic Number: This is the number of protons an element has. Answer: 26 Atomic Mass: Ignoring electrons, which are incredibly small and don't have much of an effect on the mass... This is the number of protons plus the number of neutrons Answer: 56 (26 protons + 30 neutrons) Net Charge: Protons are positive and electrons are negative. The net charge can be found by subtracting the number of electrons from the number of protons. 0 is neutral. Answer: +3 (26 protons - 23 electrons).


An isotope of an element with a relative atomic mass of 65 amu and 35 neutrons has a charge of 2 plus How many electrons does it have?

An isotope with 35 neutrons and a charge of 2+ means it has 33 electrons (atomic number - charge). The atomic number can be calculated by subtracting the number of neutrons (mass number) from the relative atomic mass, so in this case, the atomic number is 30 (65 - 35).


Is there any relationship between atomic mass and number of proteins and electrons?

Yes, there is a relationship between atomic mass and the number of protons and neutrons in an atom. The atomic mass is approximately equal to the sum of the number of protons and neutrons in an atom, as electrons have negligible mass compared to protons and neutrons. The number of electrons in a neutral atom is equal to the number of protons, in order to maintain a balanced charge.


How many protons and electrons are present if the atomic mass is 18 and has 8 neutrons and a charge of -1?

atomic mass = protons + neutronsprotons = atomic mass - neutrons = 18 - 8 = 10 protons (Neon)In ground state, protons = electrons = no charge-1 charge means gain of 1 e-, so number of electrons = 11 electrons


How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?

Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.


How many electrons and What is the atomic mass and number in chlorine?

17 electrons - atomic mass 35.5 and atomic number 17


What and what make up the atomic mass?

The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. Protons have a positive charge and neutrons have no charge, contributing to the overall mass of the atom. The number of electrons, which have a negligible mass, is not included in the atomic mass.


How do you calculate the number of proton neutron and electron using atomic no and mass no?

To calculate the number of protons in an atom, use the atomic number (Z), which represents the number of protons. The number of neutrons can be calculated by subtracting the atomic number from the mass number (A = Z + N). Electrons are the same as the number of protons in a neutral atom.


How do you find electrons?

you can find electrons by subtract the atomic number and atomic mass.
