Atomic Structure
| Particle | Charge | Mass (amu) |
|---|---|---|
| Electrons | -1 | 0.000549 |
| Protons | +1 | 1.00782 |
| Neutrons | 0 | 1.00867 |
Does atomic mass change with charge?
Explanation: An atom’s mass number tells you how many protons and neutrons said atom has in its nucleus. Gaining or losing electrons has no impact on the number of protons and neutrons an atom has, which is another way of saying that the mass number is not affected by changes in the net charge.
What element has a mass number of 69 and 38 neutrons in the nucleus?
Minus number of protons, which is 31. And that gives us roughly 38 neutrons. Neutrons for for gallium that has an atomic number are atomic mass of 69. Okay, for the other one, we have 70.9 to 5 for the atomic mass.
Can thulium be cut with a knife?
Thulium metal is soft, malleable and ductile, and is so soft that it can be cut with a knife. The first compound containing Thulium was discovered and named by Swedish Chemist Per Teodor Cleve (1840 – 1905) in 1879.
What does a +1 charge mean?
+1 on an atom indicates that,there is a deficiency of one electron. generally protons are positively charged and electrons are negatively charged and are present in equal ration making an atom neutral if electrons are missing positive charge is created and if excess electrons are added the atom is negatively chargeed.
How do you know what the charge of an atom is?
For a single atom, the charge is the number of protons minus the number of electrons.
What atomic particle has no charge?
The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge.

What is the charge of a neutron?
A neutron is a slightly heavier particle with a mass 1.0087 amu and a charge of zero; as its name suggests, it is neutral. The electron has a charge of 1− and is a much lighter particle with a mass of about 0.00055 amu (it would take about 1800 electrons to equal the mass of one proton.
What is the charge of a neutral atom with Z 8?
A neutral oxygen atom (Z = 8) has eight electrons, and if it gains two electrons it will become an anion with a 2− charge (8 − 10 = 2−). Composition of an Atom Iodine is an essential trace element in our diet; it is needed to produce thyroid hormone.
