Acertain element forms an ion with 36 electrons and a charge of +2. identify the element

The element is Strontium.

Explanation:

Atomic number is defined as the number of electrons or number of protons that are present in an element.

Atomic number = Number of protons = Number of electrons

If an element has a positive charge, it means that the electrons are lost which were earlier present.

Thus, the total number of electrons in the given element becomes = 36 + 2 = 38

And the element which has 38 electrons means that it has an atomic number of 38.

Hence, the element is Strontium.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
