Answer:
hydrogen atom but see the note below.
Explanation:
This is either the most common hydrogen ion or a hydrogen atom. It cannot be either of hydrogen's isotopes.
Antimony Sb
Explanation:
The element that will have similar chemical properties with Arsenic As is element Antimony or Sb.
An element is a distinct substance that cannot be split-up into simpler substances. They are made up of only one kind of atom.
- The chemical properties of an element is determined mostly by the number of electrons in its outermost shell.
- This is called the valency of an element.
- Element having the same valency behaves the same way chemically.
- They exchange the same number of electrons during chemical reaction.
Therefore, elements in the same group on the periodic table have the same chemical properties.
Elements in the same group have the same valency.
Anitmony and Arsenic belongs to group 5 on the periodic table. The elements in this group are Phosphorus, Arsenic, Antimony and Bismuth.

Explanation:
the further down the group you go, the larger the radius becomes. its caused by the amount of electrons needed to equal out the charge of the nucleus
A cookie made from flour, eggs, sugar, butter, and chocolate chips is an example of a heterogeneous mixture.
Also, mixing the sugar flavoring in water, since you're mixing two different states of matter.
