What element has 16 neutrons?
PHOSPHORUS
Which element has 15 neutrons?
Phosphorus – P
What is the ion symbol for an atom with 20 protons and 18 electrons?
Ca2+ represents an ion with 20 protons and 18 electrons.
What is the symbol for the ion with 19 protons and 18 electrons?
The symbol for the ion with 19 protons and 18 electrons is K+.
Does chlorine have 19 neutrons?
Chlorine 36 (Cl-36) is the chlorine isotope whose nucleus consists of 17 protons and 19 neutrons. It is a cosmogenic radioisotope of chlorine with a trace half-life of 301,000 years in the environment, in a ratio of about 7 × 10-13 to 1 with stable isotopes.
What is the charge of 19 protons and 18 electrons?
The charge on the ion is +1. The element is Argon.
What is the charge of an ion that contains 16 protons and 18 electrons?
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 18 electrons, its net charge is 2–.
Which element has a charge of when it has 18 electrons?
chlorine ion
What is the symbol of an ion with 15 protons 16 neutrons and 18 electrons?
By referring to a periodic table or table of elements, we see that phosphorus (symbol P) has an atomic number of 15. Thus, each atom has 15 protons. The mass number of the ion is 15 + 16 = 31. Because the ion has 15 protons and 18 electrons (three more electrons than protons), its net charge is 3-.
Why is the symbol for beryllium be?
Beryllium is a chemical element with the symbol Be and atomic number 4. Because of its low density and atomic mass, beryllium is relatively transparent to X-rays and other forms of ionizing radiation; therefore, it is the most common window material for X-ray equipment and components of particle detectors.
What makes beryllium unique?
Uniquely strong and light, beryllium is used to make cell phones, missiles and aircrafts. Steel gray in color, beryllium’s modulus of elasticity is about one-third greater than steel. Beryllium is nonmagnetic and resistant to concentrated nitric acid.
