What is an object that has an equal number of protons and electrons?
neutral
A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.
What happens when the number of protons and electrons are the same?
Explanation: If the number of protons is the same as the number of electrons, the particle will have no charge. If atoms gain electrons they become negatively charged ions. These are also called anions.
What type of atoms have the same number of electrons and protons?
Atoms are neutral in electrical charge because they have the same number of negative electrons as positive protons (Table 2.4. 1)….Atomic Number.
| Name | Hydrogen |
|---|---|
| Protons | 1 |
| Neutrons | 0 |
| Electrons | 1 |
| Atomic Number (Z) | 1 |
When the number of electrons and protons are not equal then the atom is?
In an electrically neutral ATOM, the number of electrons equals the number of protons. However, an ION is an atom (or group of atoms) which has either gained or lost some electrons, so for an ION the number of electrons does not equal the number of protons.
Does number of protons equal neutrons?
For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons. Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146).
Why is the number of protons equal to the number of electrons?
Actually the proton and electron count of an atom are equal only when the atom is neutral in charge. The electrons are found in orbitals surrounding the nucleus. In order for the atom to remain electrically neutral the protons and electrons must balance each other.
Can a proton exist without an electron?
So an atom can’t have no electrons as it, by definition has protons and to be neutral must have electrons. You can have an ion, such as a hydrogen ion (you might call it a proton). These are extremely reactive and can only exist in the gas phase or at extremely low temperatures.
How is the number of electrons in an atom determined?
For a neutral atom, the number of electrons is the same as the number of protons. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in an ion if you know its charge. A cation carries a positive charge and has more protons than electrons.
Are there always protons neutrons and electrons in an object?
Answer: No, there are always protons, neutrons, and electrons. When an object is neutral, it means the positive and negative charges sum to zero (are equal and opposite). NO, if an object has no net charge it simply means that the amount of positive and negative charges (protons and neutrons) are the same.
What happens to an atom when there are more electrons than protons?
If there are more electrons than protons (i.e. a gain of electrons), then the atom will be negatively charged. Conversely, if there are more protons than electrons (i.e. a loss of electrons), then the atom will be positively charged. If the number of protons is equal to the number of electrons then the atom is neutral and no net charge exists.
How is an element defined by its number of protons?
Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons.
