What is 39 in potassium?
39 is the atomic mass of one atom of potassium. This is essentially the weight of one atom
What atoms are in potassium bromide?
Potassium bromide has the formula KBr and it contains one atom of Potassium (K) and one atom of Bromine (Br).
How does potassium -39 different from potassium -41?
Potassium 31 is potassium's normal state, the way you would find it on the Periodic Table. I presume potassium 41 is an isotope of potassium. (An isotope is the same atom, but it has a different number of neutrons, so the mass differs.)
What is the mass number and symbol of an atom that contains 19 protons 19 electrons and 20 neutrons?
The mass number is always the sum of the numbers of protons and neutrons and therefore is 39 in this instance. The atomic number of 19 shows that the atom is of the element potassium, and its symbol is 39K.
What is the symbol and name for the cation formed when a potassium atom loses one electron?
The symbol for the cation formed when a potassium atom loses one electron is K+, and is named the potassium ion.
What is 39 in potassium?
39 is the atomic mass of one atom of potassium. This is essentially the weight of one atom
How much mass is in potassium?
Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.
Atomic mass of potassium atom?
39.0983 or 39
When a potassium atom reacts with a bromine atom the potassium atom will?
lose only one electron
What is an atom of potassium's atomic number and mass number?
The atomic number of potassium is 19.The atomic weight of potassium is 39,0983(1).The mass number of the isotope potassium-39 is 39.
What atoms are in potassium bromide?
Potassium bromide has the formula KBr and it contains one atom of Potassium (K) and one atom of Bromine (Br).
What is the mass number of an atom with 19 protons and 20 neutrons?
The element is potassium. Atomic mass is 38.
What are the atoms in one molecule of potassium hydroxide?
The chemical formula of potassium hydroxide is KOH: 1 atom of potassium, 1 atom of oxygen, 1 atom of hydrogen.
What is molecular mass of potassium in potassium chloride?
Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.
How does potassium -39 different from potassium -41?
Potassium 31 is potassium's normal state, the way you would find it on the Periodic Table. I presume potassium 41 is an isotope of potassium. (An isotope is the same atom, but it has a different number of neutrons, so the mass differs.)
What is the mass number and symbol of an atom that contains 19 protons 19 electrons and 20 neutrons?
The mass number is always the sum of the numbers of protons and neutrons and therefore is 39 in this instance. The atomic number of 19 shows that the atom is of the element potassium, and its symbol is 39K.
How many elements in potassium chloride?
There are two elements in potassium chloride. One atom of potassium and one atom of chlorine react to form potassium chloride.
