Anew element has been discovered. newelementium has 40 more protons than radon. it also has the same number of protons and neutrons. what would newelementium’s atomic number and atomic mass be? (use the periodic table)

Atomic number would be 126 and atomic mass 252.

Explanation: The atomic number is the number of protons in the nucleus of an atom. This number is the position they occupy in the periodic table.

On the other hand, the atomic mass is obtained by adding the number of protons and neutrons of a given nucleus.

Consequently, if Newelementium has 40 more protons than radon and acoording to the periodic table radon has 86 protons, the atomic number is calculated as follows:

1. 86 + 40 = 126

Newelementium would have 126 protons, therefore its atomic number would be 126.

Since Newelementium has 126 protons and the same number of neutrons, its atomic mass would be:

2. 126 (protons) +126 (neutrons) = 252

Newelementium atomic mass would be 252.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
