What is the mass number of 4 protons 5 neutrons and 4 electrons?

What is the mass number of 4 protons 5 neutrons and 4 electrons?

So, for beryllium, there are 4 protons, 5 neutrons and 4 electrons but to calculate atomic mass number, four electrons won’t be counted. Hence the atomic mass number of beryllium will be the sum of 4 protons and 5 neutrons and that will be equal to 9.

What is the atomic number of the atom that has 4 protons 4 electrons and 6 neutrons?

Atomic Number

Name Protons Neutrons
Lithium 3 4
Beryllium 4 5
Boron 5 6
Carbon 6 6

What is the charge of an atom with 4 protons 5 neutrons and 4 electrons?

The atomic mass is expressed by the number of massive particles, protons, and neutrons, and since we have 5 neutrons, the isotope is 9Be . Finally we can assign the charge. There are 4 protonic charges, and 4 electronic charges: the isotope is neutral.

What is an atoms atomic number if it has 4 protons 4 neutrons and 4 electrons?

beryllium
The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons. Varying the number of neutrons changes the isotope of beryllium, while varying the number of electrons can make beryllium ions. The symbol for atomic number 4 is Be.

What is the mass of an element that has 5 protons 6 neutrons and 4 electrons?

In this case the mass number would be 11.

What is the likely atomic mass of an atom that has 4 protons?

Since it has 4 protons, it must have an atomic number of 4. (That makes it beryllium.) Since it has a 4 protons and 5 neutrons, it has a mass number of 9.

What atom has 4 protons and 4 neutrons?

The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons. Varying the number of neutrons changes the isotope of beryllium, while varying the number of electrons can make beryllium ions.

What is the mass number of an atom with 3 protons 4?

What is the mass number of an atom with 3 protons 4? Lithium, for example has three protons and four neutrons, leaving it with a mass number of 7.
