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 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 neutrons and electrons does an oxygen atom have?
Oxygen has 8 protons . The number of neutrons depends on the isotope. Oxygen-15 isotope has 7 neutrons and oxygen-16 isotope has 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
How many protons neutrons and electrons does si-28 have?
A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the atomic mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.
What is a partical in an atom with no charge?
A particle in an atom with no charge is called a neutron. Neutrons are found in the nucleus of an atom along with protons, which have a positive charge, and electrons, which have a negative charge. Neutrons help stabilize the nucleus and contribute to the overall mass of the atom.
What are the changes of protons nutrons and electrons?
Protons and neutrons are found in the nucleus of an atom and have approximately the same mass, while electrons orbit the nucleus and have a much smaller mass. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. Changes in the number of protons determine the element, changes in the number of neutrons result in isotopes, and changes in the number of electrons create ions.
What is the mass number of an ion with 108 electrons 157 neutrons and a 1 charge?
you didnt specify whether the charge was positive or negative :(
What particles are added together to determine atomic mass?
The atomic mass of an atom is determined by the sum of the number of protons and neutrons in its nucleus. Protons have a positive charge, and neutrons have no charge. The total number of protons and neutrons in an atom's nucleus is called its mass number.
What is the mass number of an ion with 107 electrons 159 neutrons and a 1 charge?
266
What identifies the number of an atom?
An atom consists of protons (positive charge), neutrons (no charge), and electrons (negative charge). The atomic number is the number of protons. Furthermore, the mass number is the sum of the protons and neutrons.
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.
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.
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).
What is the mass number of an ion with 107 electrons 159 neutrons and a plus 1 charge in integer form?
If the ion has a +1 charge and has 107 electrons, that means that it originally had 108 electrons, and therefore has 108 protons. The mass number is the sum of the protons and neutrons, 108 + 159, and therefore is equal to 267.
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 find the mass number of an atom that has 3 protons and 4 neutrons and 2 electrons?
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 3 protons and 4 neutrons, so the mass number is 3 + 4 = 7. Electrons do not contribute to the mass number as their mass is negligible compared to protons and neutrons.
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.
