What is an atom with 4 protons 5 neutrons and 4 electrons?
4 protons, 5 neutrons, and 4 electrons are there in an atom of beryllium.
What has 4 protons 3 neutrons and electrons?
Lithium, for example has three protons and four neutrons, leaving it with a mass number of 7.
What is the mass number of an element whose atom contains 4 protons 4 electrons and 5 neutrons?
Beryllium
Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons. Since 2 + 2 = 4, we know that the mass number of the helium atom is 4….Mass Number.
| Name | Beryllium |
|---|---|
| Symbol | Be |
| Atomic Number | 4 |
| Protons | 4 |
| Neutrons | 5 |
What is the total charge of an atom that has four protons and three neutrons and four electrons?
zero
So our final answer is that the atom which has four protons, three neutrons, and four electrons has a relative charge of zero.
What is the Amu of an atom that has 4 neutrons 4 protons and 4 electrons?
Atomic mass of Beryllium is 9.0122 u. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams.
What is the total charge of 4 protons 5 neutrons 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.
Which is the neutron number?
Atomic number (proton number) plus neutron number equals mass number: Z + N = A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z….Neutron number.
| Element | C |
|---|---|
| With atomic number | 14 6C |
| With neutron number | 14 6C 8 |
What is the atomic number of neutral atom with 5 neutrons and 4 electrons?
beryllium
(Round the atomic mass from the periodic table to the nearest whole number to get part of your answer.) From the periodic table, beryllium has an atomic number of 4 and a mass of almost 9 amu. Therefore, a neutral beryllium atom has 4 protons, 4 electrons, and 5 neutrons (# neutrons = mass # – # protons).
What is the atomic mass of an atom that has 4 protons 4 neutrons and 4 electrons?
Atomic mass of Beryllium is 9.0122 u. The unit of measure for mass is the atomic mass unit (amu).
What is the atomic number of an atom with 5 neutrons and 4 electrons?
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.
