How many electrons are present in bromine atom with mass number of 87?
A bromine atom, regardless of its mass number, has an atomic number of 35, which means it has 35 protons and, in a neutral state, also 35 electrons. Therefore, a bromine atom with a mass number of 87 will have 35 electrons. The mass number indicates the total number of protons and neutrons, but it does not affect the number of electrons in a neutral atom.
An atom has 29 electrons and protons and 35 neutrons what is the mass number?
30 The atomic number is the number of protons
How many neutrons are in an atom of sulfur with a mass number of 35?
Sulfur is a non metal element. Mass number of it is 32.
What is the Mass number of a bromine atom?
Bromine has an approximate atomic mass of 79.904.
How many electrons are present in a bromine atom with a mass number of 87?
A bromine atom with a mass number of 87 has 35 protons (since bromine has an atomic number of 35). Since it is neutral, it also has 35 electrons.
If a chlorine atom has 17 protons and 18 neutrons what would its mass and atomic number be?
the atomic number would be 17 && the mass would be 35
What is the mass number of a CI atom that 17 protons and 18 neutrons?
Chlorine is a non metal element. Mass number of it is 35.
What is the mass number for a sulfur atom that contains 19 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Since sulfur has 16 protons (its atomic number) and 19 neutrons, the mass number of a sulfur atom with 19 neutrons would be 16 + 19 = 35.
If the number of electrons in an atom is 35 and its mass number is 80 what is the number of nuetrons?
The number of neutrons is 45 because you subtract 80 to 35.
What is the number of neurons in the nucleus of an atom of chlorine if it has an atomic mass of 35 and an atomic number of 17?
In an atom of chlorine with an atomic number of 17, the number of protons in the nucleus is 17. Since the atom is neutral, it will also have 17 electrons. Neutrons can be calculated by subtracting the atomic number from the atomic mass, so for chlorine with an atomic mass of 35, it would have 35 - 17 = 18 neutrons in the nucleus.
Every chlorine atom has mass number of what?
Every chlorine atom typically has a mass number of either 35 or 37, corresponding to its two stable isotopes: chlorine-35 and chlorine-37. The mass number represents the total number of protons and neutrons in the nucleus of the atom. Most naturally occurring chlorine is found as chlorine-35, which accounts for about 75% of chlorine in nature.
What is the mass number of cl35?
The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.
