An atom with 11 protons, 12 neutrons, and 10 electrons is a(n): A) anion B) cation C) isotope D) molecule E) radioisotope. C (carbon, oxygen, hydrogen, and nitrogen) Ninety-six percent of the human body is composed of the elements: A) sodium, potassium, hydrogen, and sulfurThere are 5 protons in every boron atom and therefore boron-11 isotope has 6 neutrons. The sum of the protons and neutrons of an atom is equivalent to its relative mass number. 0 0 1
B. Mass Number Equals Protons plus Neutrons Each atom also has a mass number, denoted by the symbol A. The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number. 26. The total number of neutrons, protons, and electrons in 31P3-are: a. 15 neutrons, 31 protons, 15 electrons b. 16 neutrons, 15 protons, 18 electrons c. 31 neutrons, 15 protons, 18 electrons d. 15 neutrons, 16 protons, 12 electrons e. 16 neutrons, 16 protons, 18 electrons 27. Which of the following elements is a metal? a. K b. C c. N d. O e ... , atom of sodium, symbol Na, mass 23, 11 protons, 23 – 11 = 12 neutrons and 11 electrons atom of iron–56, mass 56, 26 protons, 30 neutrons (56 – 26) and 26 electrons If the proton number and electron number are different, the atom has an overall surplus or deficiency of electrical charge, resulting in an electrically charged particle ... The tumor is then bombarded with very low-energy neutrons (although often higher than thermal energy) which are captured by the boron-10 isotope in the boron, which produces an excited state of boron-11 that then decays to produce lithium-7 and an alpha particle that have sufficient energy to kill the malignant cell, but insufficient range to ... The "11" in "Boron-11" is the mass number, which is the sum of the number of protons and neutrons. So if we add the number of protons (5) with the number of neutrons (unknown), we get 11. The...In sodium atom, there are 11 protons and 11 electrons, i.e. an equal number of protons and electrons. In sodium-ion, there are 11 protons but 10 electrons, i.e. sodium ion contains a lesser number of electrons. The sodium atom has only one electron in its valence shell. Sodium-ion has 8 electrons in its valence shell. Use information about the number of protons, neutrons, and electrons to identify an element, its position on the periodic table. ... 11/13/2012 4:30:35 PM ... Boron-11, and that's how you would say it and sometimes you see it written, Boron dash 11. So, that's what you say when you see something like that. And you should stop and you should determine the number of protons, neutrons, and electrons in an atom of Boron-11.
Difference in mass of an atom and the sum of the masses of its protons, neutrons, and electrons Example 19 9 F isotope has an atomic mass 18.9984 amu. Mass of 1 1 H atom (1.007825 amu), mass of the neutron (1.008665 amu). The mass of 9 1 1 H atoms (9 protons and 9 electrons) is 9 x 1.007825 amu = 9.070425 amu and the mass of 10 neutrons is Model A switched the numbers of protons & neutrons. Model B moved an electron from Energy Level 1 to Energy Level 4. Model C is correct. Model D moved both electrons from Energy Level 1 to Energy Level 4.

To discover the amount of protons and neutrons in boron-11, one must look at its atomic number and atomic mass. Boron-11's atomic number is five, which means it always has five protons. To discover how many electrons boron-11 has, one should subtract the amount of known protons from its atomic mass of 11. read moreSep 25, 2017 · A)protons B)neutrons C)electrons plus neutrons D)protons plus neutrons 8.All atoms of a given element must contain the same number of A)electrons and protons B)electrons and neutrons C)neutrons and positrons D)neutrons and protons 9.The major portion of an atom's mass consists of A)contains protons, neutrons, and electrons To discover the amount of protons and neutrons in boron-11, one must look at its atomic number and atomic mass.

The Questions and Answers of A neutral atom (atomic no. is greater than 1) consists of: A)only protons. B)Neutrons protons C)Neutrons Electrons. A. 16 electrons B. 8 electrons C. 16 protons D. 16 neutrons _____14. Would you normally expect neon (Ne) to form compounds? A. Yes, but neon is a rare gas and difficult to obtain B. No, neon needs six electrons to fill its outermost level. C. Yes, neon needs six valence electrons to fill its outermost energy level. D. Boron-11 has 5 electrons. The number 11 represents the mass number which is the sum of protons and neutrons. If you look in the periodic table, you will notice that boron has 5 protons. So, it must have 5 electrons because it is a stable element and has no net charge. In order to calculate the number of neutrons: 11–5 = 6 neutrons
