An ion has a mass number of 65, 36 neutrons, and a charge of 1+. Identify the element symbol and determine the number of protons and electrons in this ion. What is the mass number of an ion with 107 electrons, 158 neutrons, and a +1 charge? What i...
When an atom has a neutral charge, the number of protons is equal to the number of electrons. However, when it is charged, the number of lost or gained electrons is equal to the charge. The nucleus of an atom determines its mass numbe...
Find the element lithium (Li) on the periodic table. The atomic number for lithium is 3, representing the number of protons in the nucleus of one atom. Step 2 Note that the mass number of lithium is 6.94, representing the sum of the numbers of protons and neutrons in the nucleus of on...
the researchers were looking to determine how many neutrons could be added to a nucleus before they stop sticking to one another, leading to dripping out. Such a limit is known as the dripline. Prior researchers have already found the dripline for a number of elements—all eight...
How many neutrons does element X have if its atomic number is 43 and its mass number is 161? If the atomic number of an element is 12 and the atomic mass is 25: a. How many protons are there in the nucleus? b. How many neutrons...
Calculate the number of Li atoms in 0.500 mole of C. What is the number of moles He in 8.90x1015 atoms of He. How many Br atoms are in 0.453 moles of CBr4? Calculate the number of neutrons in a bromine nucleus, which has a radius of approximately 5.38 x 10-15 m. The atom...
Determine the ratio of neutrons and protons in the nucleus of He. Determine the number of protons, neutrons, and electrons in the given species. 24Mg Determine the number of protons, neutrons, and electrons in the given species. 52Cr Determine the number of protons...
The number of protons in the nucleus of an atom of an element determine ___. The number of protons and neutrons in the nucleus of an atom of an element determine ___. How do you find the number of protons, neutrons, and electrons of a particular atom if you are given the atomic...
Dissociation of an unstable nucleus into smaller nuclei with release of a vast amount of energy is referred as the radioactive decay. The radioactive decay is further classified as alpha, beta and gamma decay. Out of these, beta decay may be defined as the emission of an ele...
Use a periodic table to determine the atomic mass and the number of protons, electrons, and neutrons for neon.Mass Number:The mass of an atom always consists in the nucleus and it is equal to the sum of proton and neutron that is present in the nucl...
