The only element with 55 protons is caesium. The electron configuration you gave is xenon's. In order to change the configuration to get 55 protons, you need to add a 6s1. Also, you listed the electron groups in the wrong order. Switch 4s and 3d, and switch 5s and 4d.
The electron configuration of cobalt is [Ar]3d7.4s2.
The element with 26 electrons and protons is iron (Fe).
An ionic bond can form between an element with 11 protons (sodium) and an element with 17 protons (chlorine) to create sodium chloride (table salt). Sodium will donate an electron to chlorine, resulting in a stable arrangement of electronic configuration in both atoms.
First, we need to add up the number of electrons in the configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10. Doing so gives a result of 30. A neutral element having 30 electrons will also have 30 protons. Checking the periodic table, we see that zinc is the element with 30 protons.
Neon is an element because it is a pure substance made up of only one type of atom – neon atoms. These atoms have a specific number of protons in their nucleus, giving neon its unique chemical properties. Neon belongs to the noble gas group on the periodic table due to its stable electronic configuration.
The electron configuration of cobalt is [Ar]3d7.4s2.
If it has 11 electrons it must have 11 protons to balance the charge. So the element is Na. But you know it's going to be an isotope of Na since the number of protons and number of neutrons are different. To find out which isotope you have, you must get the mass number which is just the number of protons plus the number of neutrons (remember, they are the only ones that have mass) 11+12= 23 So you have Na-23

Atomic number. This gives the count of protons in the nucleus and therefore the posiitive charge of the nucleus. For an uncharged atom it therefore gives the total number of electrons in all shells

according to the electronic configuration of element . if no. of electons is 35 then the element in its shell o will will have 2 electron left . 35-2 =33is the number of proton
Phosphorus has the above electron configuration. It has 15 electrons and protons.
valence electrons is the same as the number as the last digit in the group :)
The element with 27 protons is cobalt (Co). Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d7.
The electronic configuration by shell for the element Platinum is the same as the filled shells of Xenon (q.v.), plus the following added: 14 electrons in the 4f shell, 9 in the 5d shell, and one in the 6s. Note that protons do not occupy shells in the atom but are bound in the nucleus.
[Xe] 6s2 4f1 5d1.There are a total of 58 electrons. Or the atomic number is 58 and the element is Cerium
