Enter the atomic symbol, including mass number and atomic number, for iodine-130.

WINSTONCH [101]

<u>Answer:</u> The atomic symbol of the given element is $_{53}^{130}\textrm{I}$

<u>Explanation:</u>

The general isotopic representation of an element is given as: $_Z^A\textrm{X}$

where,

Z represents the atomic number of the element

A represents the mass number of the element

X represents the symbol of an element

For the given isotope: 130-iodine

Mass number = 130

Atomic number = 53

Hence, the atomic symbol of the given element is $_{53}^{130}\textrm{I}$

Which of these solids are most likely amorphous solids? Select all that apply. Rubber sugar plastic candle wax graphite glass.

Ostrovityanka [42]

The solids are characterized as amorphous and crystalline solids based on the arrangement of atoms. The solids that are amorphous are rubber, plastic, candle wax, and glass.

<h3>What are amorphous solids?</h3>

The solids have the arrangement of atoms in the lattice. The solids with an appropriate arrangement of atoms are crystalline solids. For example, sugar, graphite.

The solids with irregular arrangements of atoms in the lattice are amorphous solids. For example, glass, rubber.

Thus, the solids that are amorphous in nature are rubber, plastic, candle wax, and glass.
