Question

Write the atomic symbols for isotopes with the following characteristics? 1)an oxygen atom with 10 neutrons 2)a neon atom with twelve neutrons 3)25 electrons and 28 neutrons 4)a mass number of 24 and 13 neutrons 5)a titanium atom with 25 neutrons

Answer 1

Atomic symbols for specified isotopes include ¹₈O for oxygen with 10 neutrons, ¹₀Ne for neon with 12 neutrons, ⁵₃Mn for an element with 25 electrons and 28 neutrons (manganese), ¹₄Mg for an element with a mass number of 24 and 13 neutrons (magnesium), and ´⁷Ti for titanium with 25 neutrons.

Step-by-step explanation:

The atomic symbols for isotopes with the following characteristics are:

• An oxygen atom with 10 neutrons: ¹₈O, since oxygen has an atomic number of 8 (8 protons) and with 10 neutrons the mass number is 18 (8 protons + 10 neutrons).
• A neon atom with twelve neutrons: ¹₀Ne, because neon has an atomic number of 10, adding 12 neutrons gives a mass number of 22 (10 protons + 12 neutrons).
• 25 electrons and 28 neutrons: Since the element must have 25 protons to have 25 electrons in a neutral atom, the element is manganese (Mn) and its symbol is ⁵₃Mn for a mass number of 53 (25 protons + 28 neutrons).
• A mass number of 24 and 13 neutrons: This must be magnesium (Mg) with a mass number of 24 (11 protons + 13 neutrons), thus the symbol is ¹₄Mg.
• A titanium atom with 25 neutrons: Titanium (Ti) has an atomic number of 22, adding 25 neutrons gives a mass number of 47, so the symbol is ´⁷Ti.

Answer 2

Isotopes are elements that differ in the number in neutrons while the numner of protons are the same. The answers of the questions are: 1) 18/8 O 2) 22/10 Ne 3) 53/25 Mn 4) 37/24 Cr 5) 106/81 Ti.
