Is KR a neutral atom?

Ground State Electronic Configuration of Krypton – neutral Krypton atom.

What species contains 36 neutrons?

In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons (Figure 4). The two different kinds of atom are called isotopes of copper. The neutron has a mass very similar to that of the proton, so the two isotopes differ in mass.

What element has 34 neutrons?

An isotope of copper contains 34 neutrons.

Which atom has the smallest number of neutrons?

Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3. Hydrogen-1 has the smallest neutron number, 0.

What is the charge of an ion that has 41 protons and 36 electrons?

It is positively charged because a negatively charged electron was removed from the atom. The 35 remaining electrons were outnumbered by the 36 positively charged protons, resulting in a charge of +1.

What is the symbol of an ion with 34 protons 42 neutrons and 36 electrons?

Explanation: 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− .
