What term best describes the sum of the number of protons and neutrons in an atom?
Atomic mass
What following statement best describes the number of neutrons in an atom?
it's equal to the difference between atomic number and atomic mass number
Which best describes an atom of carbon-13?
An atom of carbon with 6 protons and 7 neutrons.
What best describes the nucleus of atom?
Nucleus is the centre of an atom and consists of positively charged protons and neutral neutrons.
Which best describes the nucleus of an atom?
The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
What pieces of information best describes the atomic number of an atom?
Atomic number = number of protons in an atom, and = number of electrons in an atom.
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
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.
What is best described as an atom?
A core of protons and neutrons surronded by electrons.
Atom X has 9 protons 10 neutrons and 9 electrons Atom Y has 9 protons 9 neutrons and 9 electrons what best describes how Atom X and Atom Y are related?
The relationship is that Y is the negative ion and X is the neutral atome of the same element. Particle X and particle Y are both atoms, and are of the same element as the number of protons (atomic number) is 9. With the same number of neutrons they are both the same isotope. Particle X is electrically neutral so is a neutral atom, particle Y has a single negative charge and is an anion. Inspecting the periodic table for aelement atomic number 9 the element is fluorine, the isotope is fluorine-19 (the only naturally occuring isotope of fluorine), X is a fluorine atom, Y is a fluoride ion.
What statement best describes the density of an atom's nucleus?
The density of the nucleus is 1000's times the density of the entire atom.
How would you describe the nucleus of the atom?
the nucleus is the control center of the entire atom the nucleus of an atom has 3 basic subatomic particles: -the electrons which orbit the outside of the nucleus, electrons have a negative charge -the protons which are inside the nucleus and have a positive charge -neutrons which are also inside the nucleus have a neutral charge because they are neither positive nor are they negative something you need to know about protons and neutrons: the mass of the atom equals the protons plus neutrons and the atomic number of an atom tells how many protons are in an atom really being in the nucleus. The nucleus of an atom can best be described as the part of the atom with the biggest mass. It contains an atom's protons and neutrons.
