Elements Compounds and Mixtures Quiz

What are atoms?

Which of the following are metallic?

Which of these properties best describes the non-metallic elements?

Elements are made up of just one type of atom.However, the atoms in elements can be arranged in different ways, these ways are : -[blank_start]Monatomic[blank_end] -[blank_start]Molecules[blank_end] -[blank_start]Lattices[blank_end]

What are the 6 monatomic elements?

In metal lattices,the atoms are only [blank_start]weakly joined[blank_end] to each other.As a result, metals can be bent and drawn into [blank_start]wires[blank_end]. - In [blank_start]non-metallic[blank_end] lattices, the atoms are [blank_start]strongly bonded[blank_end] to each other. This makes them hard and [blank_start]brittle[blank_end].

Wha are the 6 elements that make up your body?

What is the chemical formula for glucose molecule? <-------------------------- <-------------------------- <--------------------------

[blank_start]Alloys[blank_end] are a [blank_start]mixture[blank_end] of a metal with other metals or non-metals.Alloys are particularly important because they often have very [blank_start]different[blank_end] and [blank_start]useful[blank_end] properties compared to [blank_start]pure metal[blank_end]. For example:- -[blank_start]Stainless steel[blank_end] for tools and cutlery -[blank_start]Brass[blank_end] for doorknobs -[blank_start]Sterling silver[blank_end] for jewellery.

Scientists proposed that matter was composed of atoms well after STMs were invented.

John Dalton is considered to be the second person to propose the fundemental ideas behind the modern atomic theory of matter.

A scientific model is a/an ___________ idea that can be used to help make predictions or test assumptions. ____________=

All matter is composed of indivisible particles called atoms.

Although there are countless types of [blank_start]matter[blank_end], there are only [blank_start]117[blank_end] known types of atoms.Each atom has a unique set of [blank_start]properties[blank_end]. These properties can be:- -[blank_start]Physical properties[blank_end] -[blank_start]Chemical properties[blank_end]

Label the following atom with the correct names

Which of these are the subatomic particles?

Why is it that the electrons in atom don't fly off?

Answer the folowing table about the properties of subatomic particles.

A lithium atom has the atomic symbol <------------------------------------ <------------------------ Identify the:- -Atomic number= [blank_start]3[blank_end] -Mass number= [blank_start]7[blank_end] -Number of Protons= [blank_start]3[blank_end] -Number of Neutrons= [blank_start]4[blank_end] -Number of Electrons= [blank_start]3[blank_end]
