iron? (8 points)
Answer:
first change cm to m and g to kg so you will find the volume first which is 0.02 by 0.03 by 0.02 your answer is 0.000012 m . using the formula density=mass/volume take 0.094/ 0.00012 then divide
The measurement 0.025 g has two significant digits. Leading zeroes are not counted as significant.
The correct answer to the question is (b) 2. The number 0.025 g has two significant digits.
In Physics, a significant digit is any non-zero digit or any embedded or trailing zeroes in a number. Leading zeros, which are zeros at the beginning of a decimal number, are not considered significant digits. In the number 0.025 g, the leading zeros are not counted as significant because they only indicate the decimal place of the significant digits (in this case, the digits 2 and 5). Therefore, the number of significant digits is 2.

The element that has the electron configuration is Darmstadtium.
Since An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ contains 110 electrons in its electron shells.
Also, the element should be a neutral atom, this number should also equal to its atomic number. Therefore, its atomic number is 110.
The element in the periodic table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transition metal.

Answer:
Darmstadtium
Explanation:
An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ has 110 electrons in its electron shells.
Since the element is a neutral atom, this number is also equal to its atomic number. Therefore, its atomic number is 110.
The element in the period table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transittion metal. It also belong to period 7 in the Periodic table of elements.
B. number of electrons already present in the atom.
C. number of neutrons in the nucleus of the atom.
D. availability of an unfilled orbital in the atom.
