Why are number of electrons and protons in boron equal?
Boron has an atomic number of 5, which means that it has 5 protons in its nucleus. In a neutral atom, the number of protons is equal to the number of electrons surrounding the nucleus. Therefore, a boron atom has 5 electrons to balance the 5 protons.
Which atoms are considered neutral?
An atom is considered neutral when the number of protons in its nucleus equals the number of electrons orbiting the nucleus, resulting in no overall charge. This balance of positive and negative charges makes the atom electrically neutral.
Nitrogen atoms have 7 protons how many electrons are in an ion with a charge of plus 5?
A nitrogen atom has 7 protons and 7 electrons as it is electrically neutral. (An atom always has same number of protons and electrons)
How many protons and electrons are present in a platinum atom?
There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120
Why do atoms have no electric charge even though most of their particles have a charge?
Protons are positive and the electrons are negative. Neutrons are neutral. Now we have the basis of the atomic particle charges. The atomic number is equal to the number of protons which is equal to the number of electrons. So if there are five positive particles and five negative ones, they balance each other out. With the acceptation of ions but that would take too long for me to type!
An object has five million more electrons than protons What is the net charge of the object?
5*10^6 =5000000 5000000*(1.6*10^-19) = 3.125e25
What is the charge on an atom that has five protons nine neutrons and seven electrons?
It would have a negative charge, since the number of electrons - that have approximately the same amount of negative charge as the proton's positive charge in magnitude - is more than the number of protons. Neutrons have no charge (i.e. neutral).
If the atomic number of an element is five how many protons does the element have?
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.

What can be determined if you know the atomic number of an electrically neutral atom?
The number of electrons can be determined if the overall charge and number of protons are known. If the charge of an atom is neutral, then how ever many protons it has it will also have that number of electrons.

How does an atom become positive?
An atom can become positive if it loses an electron. For example if the atom had five protons and five electrons, then loses an electron, it would have more protons making it more positive than negative.
All about protons neutrons and electrons?
Protons, neutrons, and electrons are the main particles of an atom. Protons are positively charged and are located in the nucleus of the atom. Neutrons are neutrally charged and are also located in the nucleus. Electrons are negatively charged and are located in the electron cloud, which is an area outside of the nucleus. Within an atom, there will typically be the same number of protons and electrons so the atom has a neutral charge (they cancel out). Neutrons are usually also the same number, although it is not uncommon for the neutrons to have their own population.
What element has four protons four electrons and five neutrons?
There are too many electrons. This would be a negative ion of lithium-6 (stable but less common isotope) that does not occur naturally. The element with 3 electrons, 3 protons, and *4 neutrons* is lithium-7, the most common isotope. It forms a stable positive ion (2 electrons).
