Is an atom has 35 protons in the nucleus how many electrons will it have orbiting the nucleus?
Explanation: An atom is neutral as it has the same number of electrons that of protons. So, if an atom has 35 protons i.e. the atomic number of it is 35, then it will have 35 electrons revolving the nucleus.
What element has 35 protons in its nucleus?
Bromine – Br
Which element has 45 neutrons?
What has 34 protons and 45 neutrons?
How many protons are in te?
What is the overall charge of an ion that has 34 protons 36 electrons and 45 neutrons?
Answer: While the number nuclear protons as given is 34, and therefore we deal with the element selenium, there are 2 more electrons than protons, and therefore this species has an overall 2− charge. We represent this selenide ion as Se2− .
Which two atoms are isotopes of one another?
If two atoms have different numbers of protons, they are different elements. However, if two atoms have the same number of protons, but different numbers of neutrons we refer to them as isotopes.
Which two atoms have the same mass?
Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists define this amount of mass as one atomic mass unit (amu) or one Dalton. Although similar in mass, protons are positively charged, while neutrons have no charge.
What makes each element unique?
All atoms have protons, electrons and neutrons, but what makes each element unique is the number of protons. The number of protons in an atom is known as the atomic number.
Why is it called electron?
Electrons radiate or absorb energy in the form of photons when they are accelerated. Irish physicist George Johnstone Stoney named this charge ‘electron’ in 1891, and J. J. Thomson and his team of British physicists identified it as a particle in 1897 during the cathode ray tube experiment.
Who decided electrons are negative?
Are protons negative or positive?
Protons and Electrons A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.
Who discovered electrons are negative?
Why do electrons move from negative to positive?
A: Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.
Who found the nucleus?
What is the smallest thing in the universe?
Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
What happens when a neutrino hits an electron?
The same goes for a neutrino hitting an electron on the outskirts of an atom. Sometimes, during the collision with a quark or anti-quark, the neutrino may change into a charged lepton, such as an electron, a muon or a tau.
Are neutrinos dangerous?
Of all the elementary particles that we know of, neutrinos are the least harmful of them all. All charged particles, like electrons, protons, etc do interact and in sufficient quantities can be harmful. Even some neutral particles like gamma rays or neutrons can be harmful since they have stronger interaction rates.
